>>45951457>Mega Evolutions would have been more interesting if they had the same design philosophy as actual evolutions.Nope, because Mega Evolutions are temporary and are meant to be a full-powered form of the pokemon's current stage.
It'll be a waste if Mega Evolution followed the same design philosophy as actual evolutions, because they are not permanent like regular evolutions.
For instance, imagine if that Charizard was a temporary evolution and that Charmeleon is the permanent final evolution. Without the megastone, you'll never have that cool dragon evolution as you partner and you'll be stuck with a red-er, taller charmander forever. That's lame.
