Which Pokemon do you want to receive a Mega Evolution come next generation, or even Pokemon Z?.
I personally want them to stop giving already OP Pokemon M-Evos (which by definition are supposed to bring more balance to the Metagame, yet you give them to already monstrous beasts like Garchomp, Tyranitar, Gengar and Lucario).
I would want them to provide some viability to some underused and neverused Pokemon like Stantler, Lapras, Eletrode, Sunflora, Ledian, Dunsparce, etc.
