I like two just because theoretically you get winner take all unifaction bouts, but yeah, who the hell cares what a silver or interim champion is, there should be just champion/s and contenders.
I am with Optimus so: Refs that are too busy, let the fighters get on with it, cheap hangers on that feel the need to hold aloft the belts with a smug look ( as if they won them ) trainers or corner men that rub or tap or caress the necks of fighters at the refs instructions, the stare down, fellows its all been done before, by better fighters than you, no skirts, keep to the old fashioned shorts please, no throwing insults ( or tables at the press conference, when you win, no need to go to all 4 corner posts, and thump your chest, you won , we get it, we dont need to know ( or care ) which god you pray to, and lastly leave the fam and kids at ringside.
