I'm assuming they'll fix the MBLOCK glitch and make all the evade and block attributes actually work the way they were supposed to. In a way I want that, but part of me enjoys the awesome stuff you can accomplish by exploiting those things a little too much to be completely happy about it.
Yeah, having Cid actually do something for all your effort would be nice. I always thought it was funny that he just hangs out on the solitary island even after you're all pimped out in your airship and stuff. I mean come on...really?
Um...I guess a bonus endgame dungeon a la FFIV Advance would be nice, but nothing story altering, please. If anything has to be altered, it should be the ability to do things aside from save Celes in the South Figaro basement.
