Kenshi is the best zoner imo because he is very safe and has great armor moves. I do agree with pig too, he isn't easy to use at all, but if u play him right he is very dangerous.
Glad I'm not the only one. *cough cough Frost cough cough*
Pig & Blackula make him look easy, but you really do need surgical precision with his zoning to be successful. Once my Quan's a little more solid, he's my next project. Like Petey said, his meter management is sooooooo much more important than with the other characters I play. But there's too many people he can shut down not to put the time in to him.
I agree with what fly says. I just have no real mu exp vs a nw then again I don't have much mu exp vs most of this cast right now. I just don't play enough. Street fighter has kinda taken over.
