I've been running into a high # of trooper premades.
Heavy armor, I have a feeling all 31/10 spec'ed, healers.
Some have the spec'ed no-interrupt bubble.
There doesn't seem to be any particular good way to fight groups of these. They can simply outheal any damage. Get one almost dead, they pop their bubble, and i imagine crit heal themselves for 3-5K repeatedly uninterruptable.
They don't have to move. They dont have to kite. They just stand there.
Ideas? Seems the only thing to do is start bringing my own premade.
