I saw several high level players counter rufus with rog and have some success
Cammy has been my go to fun character since vanilla. I guess I ought to think about leveling her up some. =p
I love using Sim, but I do agree if you’re going to sub someone it should be a character you both enjoy – and makes up for your main’s shortcoming. I need offense and good reversals.
One characters I’ve had a surprisingly high amount of fun with was Bison. It took me a while to get down his BnBs, I still need improvement though. Bison has amazing pokes and normals, so a Sim player won’t feel like a fish out of water with him. The concept of using a charge character took me some time to get used too, but I can confidently say hes my sub and I’m enjoying every match.
I said Akuma, but It’s too difficult to menage, so I’ll pick Balrog. He has a lot of tricks, he’s not so boring as I thought.
