For the ******* cracking down on Ambrose' G&W, please stop talking. Not only are you basing your opinions on one video, but your reasoning is out to lunch. Using Bair repeatedly vs Jigglypuff is bad? Are you kidding? Jigglypuff can barely get past it. Ambrose is an exceptional player.
Also, as for the Roll Out spam, Roll Out is harder to counteract than you think. It's more of a psychological move than anything. If it hits you, you're dead, regardless if it's on the start of the move, or just as it ends when it seems harmless. It also eats shields. Since Jigglypuff is so underused, people do not have a solid idea as to what exactly out prioritizes it, or even how to counter it. Jigglypuff is one of my best characters, and I faced him in pools. Even I didn't know how to beat him exactly, or the Roll Out, and I was the only person who thought he was good until he 2-0'd everyone. I didn't underestimate him, and I still lost.
Anyway, with that said, this individual is good. This was apparently his first tournament, and the GTA players were awesome too. He also has a G&W that I didn't get to see.
