>>42675347Megas are functionally just new pokemon.
They don't fundamentally change the way the game is played, because you don't play differently against a mega than you do any other pokemon.
Z moves are just gems but more bullshit. They shoulda been a bit less strong or limited to only STAB moves or something. The support Z moves are really cool though.
Dynamax is just shit. Makes setup braindead and revenge killing stuff a coinflip.
