>Gen 5 Exp. scaling to make over leveling harder>stronger gym leader/E4/champion teams>more Mega EvolutionsPotentially: Chesnaught, Delphox, Greninja, Butterfree, Slowking, Fearow, Golem, Machamp, Froslass, Dragonite, Florges, Mew, and a couple others
>expanded region (Southern Kalos/Southern France)>more customization options>Zygarde cell/Zygarde Complete form storyline>post-game battle facilities (Battle Factory and Pokemon World Tournament would be my picks)>power plant areas in the desert open up and have a sidequest >clean up Lumiose navigation and improve available activities>Pokémon Contests from Hoenn make it big in Kalos (it would be really fitting)>nerf the more overpowered mega evolutions and buff the weakest mega evolutions so they’re more balanced and lead to more varied teams where nearly any mega evolution is equally viable>Red, Blue, and Green cameos + battles>PokeNav+ with DexNav, etc. added to Kalos
