i liked the shortcut system in kh2 a lot, actually... much better than trying to use items in kh1. thing is, if i set items in my deck, i sometimes end up mashing buttons and wasting items, which isn't something i'm a big fan of. i have to scroll past them to not use them when i don't need them, which kind of throws me off. that's really my only gripe with the whole battle system.
