Hardly does anything. She's not a new leader. If you run zFinn and Poe, she can lock out some toons quickly and I always call trooper to assist for the expose chance. I'll wait and see if someone can make an awesome team with her but at this point, she can't do anything that other toons can't do better. She's like zQGJ lead as the only Jedi, the foresight and buffs/debuff s are mildly annoying.
Give her expose on basic, and since she has an "I can do that" in the movie, her mind tricks should do what they do now, be AOE, and copy all other debuffs on the team (or at least different ones like Cassians crippling shot) - while cleaning the team - so the *team* can get cool downs on hitting exposed enemies, not individual toons. A random enemy gets exposed for each cleaned ally. Her other attack should also remove all buffs.
