Play a tank, it does slow the run down a bit only having 1. But 7 people > 1, no changing that, and honestly the fights are so over-cheesed now that your never going to experience them anyways unless its on undersized minilvl as it is. Sometimes I sit in the AoEs on the 2nd Ultima fight when I heal just cause. Other than that, the best option you have is make a PF for going in with CS watching as others have mentioned.
