>>27350331Game Freak doesn't give a shit about game-breaking changes -- Mega Kangaskhan, Mega Salamence, Fancy Rayquaza, etc. are all proof enough of this.
I suspect mega evolutions are replacing normal evolutions for two main reasons: 1) mega evolution is a flashy gimmick, and 2) everyone complained about all the out-of-gen evolutions in gen IV (even if mega evolution ruins someone's favourite Pokémon, it doesn't do it as "irreparably" as an actual evolution).
I suspect the first reason is far more responsible for the lack of out-of-gen evolutions.
