Because it's fun, let's compare this to FD!
The "above average usage" characters on FD are MK, Snake, Falco, Marth, Dedede, Pikachu, Olimar, Sonic, ZSS, Diddy, G&W, Fox, ICs, and Pit
Are you seeing a pattern? :B
Here's a graph of all the characters.
Snake and MK seem to be the most telling; look at the complete inverse trend going on! G&W seems to do just as well on SV and FD, but excels on Norfair. Wario gets DESTROYED on FD. Seems like a lot of people do. Fox certainly does well there though.
But if you'll notice, almost across the board, FD and Smashville are the exact same as far as what characters will do well there. A few characters, like Fox, Olimar, and Sonic, really get hurt by that floating platform and prefer the room to move. (ICs always get it banned on them)
Norfair is almost the opposite in terms of what characters prefer it when compared to FD... and FD actually has MORE onesided matchups and more increases.
In other words, FD is more one sided and unfair than Norfair, so if you ban Norfair and not FD you're a bunch of hypocrites.
Here's the list of the characters that can are used "above average" on all 3 stages (you'll notice this list is getting shorter)
Diddy
Falco
G&W
MK
Pikachu
Pit
Snake
ZSS
And here's the graph:
it's important to note that Diddy isn't very common; this is due to the bans on FD, as one can imagine.
