I'd like the world to be "more 3d". XY kept the camera and movement about the same as before. I'd like a full 3d explorable world, with proportional characters (like when we see when a battle starts/ changing clothes). A pokemon following you, like in yellow/hgss would be great.
Minor details, like being able to nickname pokemon you get from a trade. Inovative pokemon: a pokemon with 3 types or two abilities, maybe an ability that let's the pokemon learn 5 moves or that let it use two itens. Events pokemon being available forever. Special based rock type pokemon + a good special rock move. A great and more mature storyline. lot's of stuff to do post game. Many secrets to find when exploring.
edit: more customization, both for your avatar and pokemon. evolutions for poor pokemon, such as ledian and dunsparce.
