Okay so two things.
One - I have her at 7 stars. Her skills are maxed. If I lead with her I never dodge or deflect 80% of the time. When I play against someone else leading with her I can go through every heal I have 2 or 3 times and by then my toons are dead because I cannot hit them. At all. Ever. Even if this worked for me it would be boring. (Also keep in mind that if they aren't Jedi then her teammates should only get 6.5% evasion. Not 90%.)
Two - even when the enemy is not leading with Luminara or another toon that grants evasion, Luminara still can't hit the side of a friggin' barn. I have to use her for her heal. but having her in there is almost as detrimental to my offense as Barriss, whom I also use for her heals and health but her offense is like throwing a tissue at someone.
Whats the deal man???
