>>30389689Well, it can kinda be forgiven in Gen 5, they wanted to do a whole semi-reboot, by only giving you brand new Pokemon during the main game, and saving previous gen mons for the postgame, hence why we got so many new Pokemon, for better or worse.
Gen 6 was kind of inexcusable, especially since we got Sylveon and NOTHING else. I know it's been said a billion times, but I'm sure Mega Evolution has quashed 95% of any chance for cross-gen evos. 3-stagers like the starters, pseudos, and crappy families like Beedril and Pidgeot getting Megas is fine and dandy, but shitty to mediocre mons like Audino or Camerupt are doomed to never "truly" being salvaged through evolution.
The only chance would be if Gamefreak suddenly retconned away Megas entirely, or retconned them into proper evolutions for 1 and 2-stagers. Gamefreak is clearly extremely hesitant to retcon ANYTHING, however, as evidenced by Eevee still evolving into Leafeon and Glaceon via the Moss Rock and Ice Rock, instead of the Leaf Stone and newly added Ice Stone.
