I would say it's a solid -2 for Wario IMO. Wario has a difficult time due to how safe he has to play and the fact that one mistake on warios part can be big damage, but the thing about wario is, that he's one of the characters in the game that can be insanely safe. With a godly airspeed, quick/almost lagless aerials, true combos, cgs, an air grab, AND the ability to get a projectile, he can play a really great hit and run game and rarely put himself in harms way. No to mention he's hard to kill with a heavy weight, small size, great recovery, and tons of options from practically everywhere. The only reason I'd say -2 is because of the just plain massive amounts of damage D3 gets off one grab, especially due to how easy it is to grab with him. One grab can completely reverse a **** ton of warios efforts and can also lead into powerful kill moves that also shut down warios survivability which is another one of warios strong points.
