>>22775910Megas should be limited to Pokemon who aren't pseudo-legends and are on their third stage of evolution. So starters, Ampharos, Aggron, Beedrill, Pidgeot, Alakazam, Gengar, Gallade and Gardevoir. Most of the other ones could've been great cross gen evolutions (especially since that means they can both boost HP and they won't have a +100 BST boost, plus since they're not megas, they don't need 100% broken abilities)
I do really like the concept of Mega legendaries though. Diancie is probably my favorite, Mewtwo needed a boost after three generations of neglect losing to Arceus, and Kyogre/Groudon really needed the buff just to get past the Drizzle/Drought nerfs
