Wario is probably going to get nerfed eventually. :V
At least I think so.
Just go Marth and problem solved >_>
Wario in a nutshell:
He has little range and gets abused by disjointed hitboxes.
He has no way of dealing with projectiles or any of his own (minus bike parts, but I'm not going to count them because he can't use them at any given moment like other projectiles)
He has a good recovery in terms of distance but its pretty predicable and if you can intercept the bike jump he is a sitting duck.
He has a good combo game and can combo into kill options, heavy and floaty (a real wtf combination in Smash) making him hard to kill and fairly hard to combo, super armor in all the right places, and bite is so sexy when it comes to abusing extended hurtboxes. Add on his ability to just outcamp and run the timer any problem matchups (his mobility coupled with airdodges gets him through like anything... running the timer sucks but its something you just have to do sometimes with Wario...).
He is certainly one of the best in the game, I think its just whether the WBR feels his weaknesses compensate enough for how **** good everything else is. I wouldn't want to see anything happen to him besides maybe some damage nerfs though.
I will admit myself as a Wario player about how retardedly good comboing into a fully charged Waft for 42% plus whatever the combo into it did. The fact that he can nearly instantly put like 70% or more on any character is a bit overkill. I don't even use a fully charged Waft to kill because its so much easier to take the 42% and then jab cancel a Fsmash or something to kill. And when a perfectly timed Waft can kill around 70% (~50% no DI on Mario) it might not be the worse idea to have Wario take a little longer to build up that percent.
