I can literally almost stay off the screen on a Rift guardian, with electrocute going and the passive paralysis as well as energy armor, it does a pretty good job of stun locking - have not had a problem.

The monk combo I suggested. Tried it out further last night, got some upgrades gear, sitting between 220-350k dps per monk and only running Expert ( I know terrible ) but it is blowing through it smoothly. I have practically no Life per Hit or Life per Second and I have no trouble staying alive at all, I have a group 50k heal every 3 seconds, as well as inner sanc lowering whatever damage I would take down 55% further. I just sit in arcane beams and whatnot. It will be interesting once I bump up the difficulty, but right now it works well because you can rush through a map very fast and your characters stay together well. On the dashing strike combo. I noticed I had to re-group a lot.
