Unlimited CAF Skill Points
I see nobody has posted this yet but there is a glitch where you can max out your fighter's skills to 100's. I just created a fighter and he is 119. Yes I know it takes away from the fun of the game online, but there is always UFC only mode and that's what I play. But when it comes down to it, for the tournaments it will level out the playing field to where skills are more important that stats.
