A small update to my above mentioned theory and worth noticing.
Just faced #1 rank and top spender (lvl 60) on my server. His squad:
Old Ben 6*
Darth Vader (? Star)
Barriss 6*
Ashoka 7*
QuiQon 7*
I think you'll realize how much hp that gives his champs. It's a pain.
And while my squad was hitting below the 1k mark due to Ben's Mind Trick, his Barriss healed Vader THROUGH Sid Debuff for 8,6k - wish I had taken a screenshot. So Barriss certainly is still pretty legit, holy moly.
So please stop the whining until you reach endgame pvp.
