I think you guys are being pretty close-minded just because he has a different style.
Red has a point. Spamming bairs was shutting down Wario's air-game pretty well (except for that one time he daired and got clapped for it ... I hope his fingers just slipped
dair sucks). OK, it didn't work as well as well-spaced tilts would have, but it was a fairly effective brickwall. Oh yeah, and he really needs to start paying attention to stalemoves.
From what I can see, Bombsoldier just really doesn't like fighting on the ground, which is kind of a shame because that's where ROB really beats Wario, but at least we can see a different style in action.
I really liked his use of up-B. I've really been trying to incorporate this type of thing more into my game lately (not because of this video though, this is the first time I saw it).
Sidenote: Bombsoldier is the reason I dropped Falco as my main in Melee. When those vids of him vs Ken's Marth came out, there was a huge rush of people picking up Falco, and I just can't stand playing a popular character.
