No, A-Route Ch5 Final is still a 3 parter. After all, why would they make that easier?
As for what I'm playing, mostly just dicking around with random stuff (finishing an old FE10 playthrough, beating a few of the lamer challenges for Brawl (but not 15 Minute Melee, Marth's way too slow and clunky for that to work now, though I think a mastery of Ike Tilts will get me through) and other things that appeal to me)
Main thing I have going is still VPL, which I'm currently mucking about in Ch 7 in. Given that I've gotten the A ending cutscene, I'm now safe to send two people up again and see if I can convince Odin to like me enough to give me a free Gram. If that fails, well, hopefully I'll get enough cash to buy one. It's not exactly like I've been hurting for cash ever since I beat Lezard's Tower and made the game weep. After beating the main game I'll likely put the Seraphic Gate and Voice Collection Collecting on hold for a XF replay, non new game plus. After all, people keep on saying that 2-1 is a bitch, and I can't recall it... at all. So, I want to refresh my memory of that just to see if I did somehow forget a frustrating battle.
