There is some interesting synergy with her and Zaalbar under Carth. When she stealths and loses taunt, Z will immediately gain taunt and retribution ( after which the stagger effects can be activated by Z's counters) giving her a chance to heal and retaunt. She also gives them a full squad cleanse option, which they don't have without her. With OR applying a lot more debuffs than Jedi, she will also usually have higher, more consistent damage with her basic.
I've had good results in some limited test battles running carth/zMission/zaalbar/juhani/nest. Canderous is in progress, at which point I'll do some more extensive testing.
