The prblem with the "Speed UpB" thing is mostly that it will only be useful if your opponent is well off-stage near the stage boundary. If they're at the stage boundary, they're probably near the top of the screen as well and you just can't fly up as quickly as you can fly over.
But hey, right place at the right time, I don't see why not try it then. I've gotten close to one of those flashy kills a couple times. On a similar but unrelated note, I never see other Wario players bike jump to harass their opponent off-stage and usually either stay on-stage or attempt bike throw shenanigans at the ledge instead. Makes me
.
EDIT: After seeing the first VC7 vid against Shadow, Chibo you should've NAired after the boost. You probably would've gotten the kill and then you would not be complaining it didn't get you any kills. UAir, what is that?
It's okay, he decided to kill himself anyway.
RE: MK
I don't see how ROB deserves to be so far down when he certainly isn't the only character in the top half of the list with a major problem with MK.
And those characters don't have favorable match-ups with Snake and Diddy to boot.
