Why do people keep saying Dsmash and Usmash suck?
IMO, the Usmash, while nowhere near as useful as the Utilt, is still a great move. It comes out fast and does okay damage with the possibility of getting a KO.
I like using the Dsmash as well for damage and getting them off the stage, not to mention punishing rolls. It's a quick attack that hits on both sides. Sure, it's average for a Dsmash, but it's solid (something you come to appreciate after playing Ganon...),and hey, that combination of traits is just what makes it fit into Mario's moveset.
The way I see it, Mario shouldn't rush for KOs. He combos them, knocks them off, and keeps them off, launching a Fsmash when the opportunity presents itself. I dunno, that's how I play him anyway, and it seems to work fairly well.
Also, I disagree to whoever said Mario is at a disadvantage vs ROB. Hell, I switch to Mario vs ROB and make life a living hell with the cape.
