This was used as justification for her nerfing. Now? Zero of the top 30 on my shard use Barriss as leader. (And nobody really runs Barriss if she's not the leader.)
I said then and maintain still that her nerfing was excessive. The fact that she has gone from often-used to almost-never-used would seem to support that. At the time it was clear she was not going to be worth her slot any more, and that's what happened. She went from really good but not OP, to relegated solely to light side and GW duty.
Meanwhile, 19 of those top 30 leaders on my shard are either Luminara or Sidious.
Quit 7/14/16. Best of luck to all of you.
