Backpedaling? What?? Dankster said sonic won with a bottom 10 character which is false. That was the discussion in the first place. No he didn't because gunslinger and to some extent marksman completely make erron a solid mid A+ tier character. The orignial discussion was on gunslinger if you kept reading the conversation.
The conversation was always about the variation used, but if we're talking character now, he's still not bottom 10 because his variations compensate for each other.
Lao, Tanya, Bo, Leatherface, CSZ, Cyrax, Raiden, Goro, Kitana, Kenshi and IMO Jax (up for debate). Here are your ten characters. Of course, added into a lot of other variations not mentioned that Erron is better against. This leaves a lot to debate, because you can't really say someone is bottom 10 based on character because this game doesn't fit that model cleanly. It's all about variation
TL;DR. I never backpedaled, you just misunderstood the conversation.
