well it IS more 'fun' with a team, not the hardest mission to do, used Hunter last night and nearly got it first go, some sneaky knight somehow got behind me @boss fight, sure it teleported?, anyway 6 or 7 'tries' later, After I chose to just switch to arc launcher I got him, adds left just vanished once dead etc, only 294 (Hunter) so unless your much lower light you'll do it solo, hope you find fire-team though.
