I like that idea! But don't most mega evolutions abilities change? Maybe they'll be exceptions
Blaziken already has Speed Boost available as an ability, so that one technically can stay the same. And I think it's possible for Gamefreak to make exceptions on a case by case basis.
Besides, can you imagine a Koffing-line evolution
without Levitate?
They didn't even get a separate Dream World ability.
Am I the only one who wants more baby Pokémon? They're so damn cute.
I don't really like them, but I can appreciate them being made to give access to more powerful Pokemon earlier in the game. I like finding Budew or Happiny because they evolve into strong Pokemon, and finding the preevolved forms is more balanced. I just have two requirements.
A.) Make the baby a pre-evo of a powerful Pokemon. We don't need a pre-evo of Jigglypuff or Pikachu.
B.) Make them available in the wild before or instead of their evolved form to give them a reason to exist.
C.) Make them breed naturally! It's so silly how Gamefreak introduced the whole Incense system instead of just changing a few scripts. It doesn't even make any sense why there needs to be a baby Sudowoodo when most of the eggs are hatching Sudowoodo.
