Long FE9 post incoming!
Finished my challenge run! (Which was, in case people missed it, to use the lowest level party on every stage, and to not allow any deaths. Laguz counted as 2x their level, to make up for the lack of promotion.)
Final stage was "Watch Ike/Ena solo things while everyone else survives" - it took me a few attempts to figure the left side of the stage was easier than the right, and I sent Ena (with a single Laguz Stone) off to the right, Ike went charging straight ahead, and everyone else went left. Once they were done there, they went to help out Ena (who could tank forever, even untransformed, but couldn't kill much) while Ike smashed things. I got to berserk Ashnard twice, failing the first time because I didn't think Ike really needed Elixirs. Turns out, he did. Second Ashnard-run, I was much better prepared, with Ike having Elixirs -and- my healers being much nearer.
Character analysis!
First things first, the levels don't mean a huge amount. I spent some time grinding near the end (I'll post turns for each stage at the end of the post) so most of the obscenely high levels are because of that.
Another thing to note is that I won't talk about anyone I didn't use for more than the stage they joined, although I will note how many kills they got in brackets. Those characters are:
Stefan, Devdan, Tanith, Calill, Largo, Tauroneo, Bastian, Naesala, Haar (1), Lucia (2), Geoffrey (4)
Lastly, I'll list levels, kills and the place in the kill totals. A ~ next to the position means they were tied for it.
Ike - 20/20, 199 kills (1st) - Look surprised, Ike is MVP. With the help of a few items near the end, Ike capped something like 5 stats (HP, Skl, Spd, Def, Res) and smashed things with Aether. The only things that could hurt him on the final stage were a couple of mages, although they tended to miss, dragons, Bryce and Ashnard. Dragons tended to get Aether'd, which meant they did 3 damage. Bryce died surprisingly easy on the second try. Ashnard was the only real threat.
Boyd - 20/4, 58 kills (3rd) - I've never been a huge fan of Boyd, but he wasn't bad here (as the kill count shows). High HP meant he could tank, although he was responsible for a LOT of resets, since he consistently died if any sword user reached him. Still, when he could hit things, they'd tend to die.
Oscar - 20/20, 46 kills (~6th) - My Oscar got pretty RNG-screwed, especially compared to the general blessing I got in this run. He generally didn't deal much damage, but doubled most enemies and was useful anyway because cavalry are fucking awesome.
Titania - 20/4, 38 kills (9th) - Early-game, Titania proved to be amazingly useful as usual by sitting around without a weapon - she gained an entire level before even getting to attack, which says a lot. Once she got to attack, she was relatively useful, although still a higher level than most, and once she left the party, she never rejoined it.
Rhys - 20/5, 3 kills (30th) (29th if you ignore Geoffrey) - I cannot begin to describe how useful healers were on this challenge. Rhys was my first promoted unit other than Ike and Volke, and for good reason. Also an absolute life-saver on the final stage where he had Purge and Physic.
Gatrie - 20/9, 35 kills (11th) - The kill count makes Gatrie look better than he was. Mostly just an iron wall, except he wasn't really great at that compared to other units. Most of the kills he did get were from hitting cats with Laguz Lance, while Soren sat behind him healing. Also almost all of those were on Moment of Fate.
Shinon - 20/10, 17 kills (21st) - Ugh. Shinon was Shinon. A few kills early on, pathetic stats once he rejoined, and I fed him experience on Twisted Tower so that I could guarantee I wouldn't have to use him for Repatriation. Ended up with half-decent stats, but that was only because I forced him to gain those extra levels at the end - he had good growths there, so would have been terrible for Repatriation otherwise.
Soren - 20/16, 52 kills (5th) - Soren took a lot of help at the start. So much feeding him experience, it almost made me question why I ever used him in previous runs. That said, once he neared promotion, he was amazing at killing, and after promoting, the ability to heal coming off that magic was absolutely invaluable.
Mia - 20/4, 43 kills (8th) - Myrmidons are goooooood. Especially when I give them Vantage/Adept. That's a really nice combination. That said, it did take a few forged weapons to make her really good, and in Repatriation, she was actually sat with 4 forged weapons (named Crumcrat, Snagrat, Smashface and Smashface II.) Still, reliable crit rate and amazingly good at evasion tanking, which is much more effective when she gets the first hit.
Ilyana - 20/20, 34 kills (12th) - See Soren, change the healing thing for extra damage. (She got insanely blessed on pretty much everything but Magic, which meant she got doubles more often than not.)
Mist - 20/5, 0 kills - Mist was.. surprisingly useless, actually. She saw most of her use as a pre-promote, and the cavalry thing upon promotion was completely redundant outside of possibly one stage?
Rolf - 20/5, 36 kills (10th) - Maybe I just had bad luck with archers on this run, but Rolf didn't achieve much either. He got off to an amazing start, hitting Lv 8 before Oscar, but then slowed down drastically, eventually reaching an endgame where he could barely deal damage to enemies.
Marcia - 20/5, 46 kills (~6th) - Marcia would have been terrible if not for flight being absolutely amazing. Extra points for Brave Lance smashing on the final stage, which saved me a few times.
Lethe - 20, 71 kills (2nd) - Outside of Ike, Lethe was MVP of the run. I wish I was joking with that. Early on, Lethe transforming on the first turn was incredibly useful, and she tore through enemies, taking no damage at all. Once mages became more common, she took a little more care to use, but could still devastate armies easily, and played well into my defensive strategies. Once I got the Demi Band, she was able to push through stages without having to worry about time restraints, but could still hold her own without it, unlike other Laguz. Amazing.
Mordecai - 11, 55 kills (4th) - Would have been almost as good as Lethe, if not for the fact that he takes so long to transform. Once the Demi Band came in, he became a whole lot better, but he was so reliant on it that it really hurt his worth. Still fantastic, but not quite what he could have been, I think.
Volke - 20/6, 13 kills (27th) - Volke was pretty terrible on this run, actually. I did get him to Lv 20 before promotion, which is nice, but he was mostly useless because I had a better thief available who was forced for every stage. (We'll get to that in a bit.)
Kieran - 20/3, 16 kills (~22nd) - Like Oscar, Kieran was incredibly underwhelming. Didn't double anything, was quite frail, and didn't deal a huge amount of damage. His biggest use was to run in with a Tomahawk, attack from range, and then run away again.
Nephenee - 20/5, 27 kills (15th) - Started off reaaaaally badly, but eventually came into her own. She was way too frail to get any use out of Wrath early on, but after promotion, she was able to take out a fair few units on her own. Something of a glass cannon, but a very good one, unlike Kieran.
Brom - 20/10, 24 kills (18th) - That kill count really under-sells Brom. That part where Gatrie failed at tanking? Brom didn't. To clarify just how awesome Brom's tanking was, he was only joined by Ike and Ena as characters who were able to take a dragon's attack on Twisted Tower.
Zihark - 20/7, 29 kills (14th) - See Mia, replace evasion with extra damage. (This is a losing trade.) Vantage/Adept is so good, it should be illegal.
Sothe - 20, 22 kills (19th) - I was really dreading having to use Sothe for this challenge. He's an awful character with slow experience gain, thanks to Blossom, but terrible stats if you remove it. And what happened? He was awesome. Early on, stealing was surprisingly useful, as I managed to grab a few free staves, Vulneraries and Elixirs. Later on, having a Stiletto made Sothe perfectly capable of grabbing kills here and there, and he was pretty integral to a few strategies. Barely hit Lv 20 on the final stage, but capped a few stats in the process!
Jill - 20/5, 26 kills (~16th) - Jill started off incredibly useful - flying is just that good. However, by the end, she'd lost any defensive use she'd had before, and didn't gain any particular offensive use to make up for it, basically making her into a slightly better version of Kieran. In other words, she acted as something of a Jeigan for me in this run.
Astrid - 20/5, 16 kills (~22nd) - See the last sentence above. Astrid started off being able to get some easy kills, and promoted earlier than most, thanks to Paragon. By the final stage, though, she was barely dealing 8 damage with a fucking Brave Bow. Very disappointing end for a character who started off so well.
Makalov - 20/5, 26 kills (~16th) - The fact that he tied Jill for kills makes him seem better than he was. He was, at the very least, better than Kieran in this run, but that doesn't make him good. He was worse than Oscar, who had a bad game, and most of his kills came either from a forged weapon or Sonic Sword vs. Generals/Knights.
Muarim - 11, 5 kills (28th) - Kills do not represent worth in any way. Muarim was an incredible tank, and was fantastic for as long as he held a Demi Band. Unfortunately, like Mordecai, his worth was very much tied to it, and stages with both of them (such as Repatriation) became incredibly awkward.
Tormod - 20/18, 32 kills (13th) - Probably the best mage in this run, Tormod had pretty horrible damage compared to Ilyana/Soren, but made up for it with the extra movement and MUCH higher speed, meaning he consistently doubled where the others were getting doubled.
Reyson - 20 - Didn't get used for a huge amount of stages because, for the few stages he was on, he was incredibly useful, and I made the most of having him, meaning he got a lot of experience. He completely mocked Twisted Tower, making the stage almost laughable.
Janaff - 12, 15 kills (25th) - Ehh. Worse of the two hawks, Janaff had better speed, but worse damage/durability, and that is an awful trade. Slightly more evasive, but not enough for me to care.
Ulki - 13, 19 kills (20th) - Extra durability goes a long way with Laguz. Could quite comfortably tank, and still doubled most things so the speed loss compared to Janaff was irrelevant.
Ranulf - 12, 14 kills (26th) - What can I say? Ranulf smashed things and smashed them well. Technically a better version of Lethe, but with MUCH less availability and transforming later meaning he prefers having the Demi Band. Ends up worse because he joins so late, and Laguz aren't as powerful at that stage.
Elincia - 5 - Barely used her. First stage with her, she was a damn liability who needed protecting. She only came back for the final stage, where the movement helped with healing Ike at the end, but she couldn't deal damage to anything.
Ena - 20, 16 kills (~22nd) - Premier tank. Only existed for a couple of stages, but was amazing for both of them. Easy to grind levels on, which meant she was insanely good during Repatriation, and I really don't think I could have beaten the stage without her there.
From best to worst:
Ike > Lethe > Ena > Mordecai/Brom > Mia > Boyd/Sothe > Tormod > Ulki/Reyson > Zihark > Rhys > Soren > Jill/Nephenee > Ranulf/Muarim > Makalov/Janaff > Marcia > Gatrie > Volke > Ilyana > Titania > Oscar/Mist/Astrid > Rolf > Elincia > Shinon > Kieran
