We wiped trying different things. We burned them down 1 at a time. Was me solo healing on my operative, a Jugg, a Sorc and a Sniper. Went Smuggler, Jumping Jackhole Jedi with 2 lightsabers, Consular, Trooper. We tried the did the consular last once when the trooper was killed by accident....he throws out a nasty aoe on a quick cast that basically decimated us, so I do not recommend trying that.
So far that has been the most fun instance I have been through. I hope the difficulty continues to go up.
