If you have UI lag, that might be on your end. I seriously have no UI lag in this game, and I just upgraded my GPU to a Geforce GT 440, since then literally no UI lag at all. Only lag I've gotten is inside of towns actually and it has been more like not receiving packets for a second. I really don't want something drastic to be changed about a battle system when there are things people can do to fix lag on their end. Especially since they said they're going to make users low end computers be able to run this game better, why couldn't wait to bitch? You wait till then, see if "they" fixed it, and then you see if you can fix it, if not then bitch. But seriously wait.
