1. Merging WEC with UFC/adding the classes below those.
Against it, of the four weight classes only the 155lbers have really assimilated into the UFC. Cruz and Aldo have both been injury prone and while the talent at 145 is impressive these guys aren't going to non-title main event a PPV. And these guys are taking away main event slots that could be better used building up fighters that will draw money.
2. UFC purchasing Strikeforce.
For it, added some much needed depth to 205 and star power to the UFC. Most of these guys have brought it coming in and the UFC was in desperate need for some new blood.
3. Deal with Fox.
For it, I like the PPV quality cards, hopefully it will move the UFC away from the PPV model. The only issue I have is 30 minutes for one fight, if they can tighten that up they might have a real winner.
4. Women's fighting in UFC.
For it, Women's MMA is fun and exciting and you have serious star power.
