One of the many aspects of pride that I loved was the 2 minute break, between rounds.  It gave the fighters a chance to get vital fluids, coaching instructions and a chance to recharge for that next round.   

Even though the UFC doesnt have that gruelling 10 minute first round I think the fighters would really benefit by having a 2 minute break verses the current 1 min break (which in reality is a third of the way over by the time they sit on the stool).   The breaks in Pride gave the fighters a chance to lower thier heart rate a bit and come out energized with less fatigue ultimately making for more enjoyable action in some cases.
