Nice thing too is you don't need the trinity setup. Healers also cc and dps, dps have utility, tanks dps. It's much more fluid. In all the groups I've done as my jugg, I've never had a problem just grabbing the first 3 who responded, someone always has heals, sometimes there's a better tank so I just dps. With every class having viable dps, 3/8 of the classes can tank and 3/8 can heal, 4 is more than enough.
