I don't see a divide, really, because all the anime and manga players have no problem tagging the LA characters, and what LA players I've seen are equally happy to tag out to anime and manga characters. For example, Dean Winchester has a lot of Eastern media CR that I've seen.

But it does seem like a lot of our remaining LA players are pulling out, either by dropping entirely or just idling. It's kind of sad, because as an anime/manga player myself, I'd love to see more diversity with some more LA canons from any part of the world, but it seems like there's more 2D media players interested in the game than LA players. :(
