Get rid of pointless HMs like Cut and Rock Smash, and replace them with some items that a Pokemon can hold in order to use those in the overworld. Seriously, in battle, they're pointless, and a waste of moves.
Make the AI smarter, seriously the trainers in X Y are so stupid, I feel like I'm battling terrible children.
Make a "hard mode", where trainers and wild pokemon actually use good attacks. And what I'd like to have, is potionless battles with hard mode. No healing at all during any battle for anyone in hard mode, will make things more challenging and actually require me to"grind" in pokemon for once. I literally almost NEVER do any "grinding" in Pokemon, I don't see the point, since battling trainers is all that's needed to get through the main part of the game. In fact, I skipped trainers, and I overlevelled gym leaders by 2 or 3 in X/Y, ridiculous.
I just want a harder Pokemon game really. If Z version brings that, then I'm OK. Or the inevitable R/S remakes even....
