For Random: Pursuit goes through FE4's version of Nihil/Mantle (Julius sez hi), if this serves as a tiebreaker of any sort.
Godlike
Fomortiis(8) vs Dragon (7) - ITD 2HKO damage against Fomortiis!
Lucina (13) vs Grima (13) - EDIT: actually taking a closer look, I think I'm more inclined to take Grima's case here (I'm suspecting Lucina's better off using Braves ANYWAY outside of less odds for Pavise procs, I guess, and Grima is likely over 2x PC HP after defenses and Dragonskin).
Naesala (9 (Boss)) vs Athos (7) - uh no
Larcei (4) vs Eirika (8) - Neither is dodging much (Larcei is very accurate, but considerably less evasive, Eirika's less accurate but dodges more at base), but Eirika only doubles if she forgoes Sieglinde - and they're essentially trading hits by then. I suspect Larcei gets an Astra string going before Eirika lands a killing blow here.
Heavy
Limstella (7) vs Cordelia (13) Limstella doesn't 2HKO and gets nearly one-rounded -at best-. And, being immobile, can't avoid counters either.
Lundgren (7) vs Ike (9) - Superior damage and WTD isn't really enough, I think? I'm inclined to see Lundgren as unable to slam those Silver Lances against ranged damage.
The Vaike (13) vs Gangrel (13) - Gangrel has 9 threat range, Vaike has 8 threat range at best. And Gangrel juuuuuuust nicks a one-rounding on even Warrior Vaike mdur. Yeah, this works, a Hand Axe/Silver Bow counter ain't really doing it even against Gangrel's egregious pdur.
Tana (8) vs Cherche (13) - I lock FE13 PCs to the class I feel they're better in. Even WTD isn't quite enough here, Tana offense is just too nuts and she still has like 40% evasion against dat Brave Axe.
Sumia (13) vs Hector (7) - Sumia baaaaaaaaaaaaaaaadly needs to one-round and she kinda can't even two-round.
Rutger (6) vs Lyon (8) - Rutger parks in front of Lyon to force-trigger a counter, thus getting three shots at a crit, and is honestly likely to dodge a blast anyway.
Gaius (13) vs Lyndis (7) - There's a pretty notable accuracy and evade difference here, unless Gaius goes for Trickster... in which case he misses the 2HKO to Lyn at base, never a pretty sight. Lyn herself 2HKOs his ass regardless, Gaius concrete durability stats are a joke in Heavy.
Middle
Brom (9) vs Henry (13) - Doesn't Nos spamming make this pretty trivial?
Nergal (7) vs Oswin (7) - Oswin may not double, but parking for forced counters once again applies. Granted, Nergal might OHKO, but I don't -think- so?
Titania (9) vs Jill Fizzart (9) - Plain better.
Valter (8) vs Chrom (13) - Oh dear.
Oscar (9) vs Eliwood (7) - Okay. Oscar can always get WTA on Eliwood and that's more or less that, I think (likely there's a durability difference too). Eli's never pulling off the Durandal unless he's going for a finisher either.
Raven (7) vs Vanessa (8) - Vanessa may well double Raven - definitely does if he tries to flip the triangle (she waves a shiny Killer Lance in this case). If he doesn't, he just can't really hit her, high Skill be damned.
Light
Garcia (8) vs Marcus (7) - Garcia, if nothing else, hits pretty hard. Doubles likely don't matter.
Ilyana (9) vs Serra (7) - Ilyana 6HKOs, Serra 8HKOs with Lightning. However, doubling just keeps this out of reach for Ilyana, and Serra -actually- 7HKOs if she swaps to Shine on her last attack. Ilyana doesn't get to land a fourth attack. Considering how much Flare sucks, I don't think it would let her even -4HKO- Serra assuming an early proc, let alone 3HKO. Serra could miss (WTD and all), but so could Ilyana, and she's actually -more- likely to. This feels fairly clear-cut.
Lucius (7) vs Morph Jerme (7) - lulz
Maribelle (13) vs Excellus (13) - Yyyyyeeeeah, I think I'm sticking with Valkyrie Maribelle.
Innes (8) vs Mist (9) - Oh dear.
