Mind as a dominator is a truly insane powerset. With perma-dom and invis you can go undetected through entire maps mass mezzing and confusing everything without being detected. Mass Mezz and confuse generate no threat or do any damage so invis doesn't drop. Fairly, you don't generate mass xp or influence gains but you do get mission accomplishments and merits, etc.. for tf/sf/trial completions. When mass confuse is on CD, a ST confuse allows you to 1 shot control bosses and LTs and move on. I just have to be careful about AOEs. Confuse is also somehow more potent on AVs that other holds.
In my playing time, Nemesis snipers, Rikti drones and Roman engineers are troublesome for detecting invisibility but I can mitigate even if it slows me down a lot. The only zone or enemy group that makes me play much more conventionally is the Rularuu.
