Granted, I realize that Tira's SoulCalibur V 2p is already anachronistic as hell, I'm not sure how I feel about Siegfried's SoulCalibur V 1p. 2ps are arguably canon anyway, and they may actually just not be at all, but it's just kinda weird to be able to use it in the past, I think. Like, I know people were asking about Z.W.E.I. and Viola parts, but even if they did come out, they'd still feel weird, or like putting Sophitia in Pyrrha's outfit or putting Kilik in Xiba's outfit.
I'm happy to see Honor Boots (but no Ring Pants?!?!), and at least they picked some of the more tasteful Lost Swords stuff to bring in, and maybe some of the new parts, like that feathers set, could be used in useful ways, but as has been said, the conflicting with existing pieces is going to be an unseen concern until they come out, so we'll see how useful this stuff ends up being. Overall, I feel like about a 6/10 initial reaction to seeing this stuff.
