They should put all the events they have from any promotion in chronological order so people can watch mma unfold the way it really did. It would for you a better story then watching each promotion in order separately. I know if I wasn't lazy I could just go back and forth myself but I jut think it would be really cool and easy for them to do. 
Does anyone know of a list with them all in order? Because that would really work just as well lol.
