5. TUF - it's a product placement frat-party at best these days.
4. Dana White's attempts to make himself a bigger star than the guys doing the work and constant trashing of both "his" fighters and those from other promotions ("Do you wanna be a fucking fighter?" No, dickhead I just travelled all the way here and got my head pounded on for fifteen minutes so that you could come in here and give your stupid ass catch-phrase....can I go home now?).
3. The PPV business model- I know it is working and has worked...I get it. I just hate it. You're asking for $54.95 to watch 1-2 fights that are worth mentioning (even though I thought a few were solid cards). I hate it with boxing and I hate it with MMA. It gets even more annoying when the UFC brass bashes fans and says they don't know what they're seeing or talking about. Even if that's true in some cases, fans pay for a product.
2. The UFC's (and US rules in general) lack of a system to stop the "human blanket" approach. I'm sure some folks will absolutely nuke me for saying this but I still love the ring and yellow card system. It allows fans to see different techniques and REQUIRES fighters to constantly look for a finish or improvement in position.
1. A real ranking system; not the "flavor of the month club." I recently told Sakara that I didn't really care about having a clear title picture; that wasn't entirely true. I think the top 5 need to be clear and concise with title shots given to those deserving rather than those in favor. I love slugfests and catchweight battles but bringing in guys and giving them an immediate shot or after one fight, it's ridiculous (unless it's a reigning champion from another org. in a "unification" style fight like Reem, Shields, etc.)
