>>19998727-ability capsule can change to hidden ability too
-breeding mini-game(s) to increase or decrease IVs. No more hidden power BS or imperfect mons. 1 or 2 breeds, assuming you don't fuck up the mini-game, and you get what you want.
-sweet scent isn't fucked up by rain
-GTS doesn't allow putting up pokemon for illegal trades. No more putting up your shiny for lvl 1 charizards.
-GTS actually has options and summery. You can see the summery of pokemon listed. No more "HAS HIDDEN ABILITY" only to trade and get shit. Options allow you to list or search pokemon based upon nature or shiny
-move tutor allows you to train previous gen moves
-events are all world wide. no more japan getting legendary or france getting exclusives
-more region specific traits on more mons. like vivillion but not always so drastic. To encourage more trading.
Lastly, and I know this will get me in some trouble with people
-Unique legendaries (arceus, etc) are locked out of multiplayer. rare legendaries (moltres, etc) are limited to one per team or they stop listening to you (like when you don't have enough badges to control a lvl 100 people early game).
