Purists. If Ben Askren can hold you down and smother you for fifteen minutes tough shit. Also, fuck the gloves, fuck 12-6 rule, bring back head butts, soccer kicks, stomps , the whole shebang. I want two 10 minute rounds, 3 for championship bouts, and no stand ups. Fuck marketability, bring on the pain. 
I'd watch it, but not many people would.
