You know, I think we’re probably fine there? Like, if there is any doubt about Metagross, then just apply the change only to White Smoke. I don’t care if they have Overheat without recoil; Heatmor and Torkoal are still not going to dominate anything any time soon. And even Metagross… well, Hammer Arm isn’t really its primary attack, and it also has the options of Bullet Punch and Agility anyway. Like, it’s a buff to a Pokémon who probably doesn’t need it, but I honestly don’t think it’s a huge one? Sure as hell pales in comparison to giving Metagross a Mega Evolution, and we were apparently fine with that.
