did this again yesterday with a guildie group in tionese/columi gear who had no prior experience, I was the only one with gear and experience. Droid went down on second try, at first the marauder wasn't fast enough on moving out from mid, and interrupts were not perfect either. Jumpy boss, again wipe first coz 2 of the guys walked into lava when trying to click the console
Last boss, 3rd try, it took some practice for the tank to manage satchels, and we lacked some dps on the second try. For the last try we managed to kill it. And there were actually upgrades looted, so it's far from waste of time. For next time with same group I'd expect no more than 1-2 wipes and a lot faster execution.
