Wario is a super well designed character in Brawl. He is also very much the embodiment of Brawl's gameplay. He is mostly about jumping around and punishing mistakes made by the adverse player. Super defensive in nature, which is reflected in his immense recovery potential (heavy weight, floaty, several moves that allowed for recovery, and super hard to gimp). Even though if you wanted to, you could go ham with him. It is just super risky because he has such short range and a subpar ground game, which is to make up for his amazing aerial game, obviously.
It's such a shame they changed his moveset in PM, because among the Brawl cast, Wario's entire kit is so clearly defined in what he is supposed to do. There's movesets that are all over the place and don't know what kind of playstyle they want, like Bowser's, but Wario's was just perfect.
And this... "agenda" for the PM devs to change things that aren't even in need of changing is what makes me so miffed about it, among other things, one of which includes the motivation to create the mod in the first place.
