No, it's not. Think about how fair everyone has treated Kabal players when it comes to tournaments... They know our character is fucked up and broken, but they smile and allow us to use him in tournaments. I think this would be a great way to treat the community back as Kabal players, think of it as a way of saying "thank you". I honestly didn't feel right being up on that stage on Dallas, I felt like I took away a possible win and achievement for someone else who deserved it way more than me. I had my time to shine already, it just really wasn't right IMO and killed all possible hype.
REO, I really hope this is a troll... >_>
As far as banning Kabal...there's one major problem. There's no reason to. Yes, he has no bad matchups. Problem is, he's not so overbearing that other characters can't compete. This is basically T4 Jin all over again. Jin was too good, but it was basically agreed that he wasn't at that point where you had no reason not to pick him. Kabal is the same way.
You guys have dealt with Kabal thus far, and with all the shit known about him and being used, there's still only really REO consistently making GFs/winning anything with Kabal alone.
As far as Kenshi goes, Kenshi loses matchups. The only big issue with him is that he is actually a character that blows out a TON of characters backs harder than Kabal does.
