I stayed in the room with the big doors that immediately open to Sepiks. There were three of us, LPERKO and Bach3000. We all stayed there after LPERKO got slammed in the left-hand room (as you enter the boss area), didn't try it after that. Captains and Vandals ran out of that left-hand room, then through the big doors where we were (this happen prior to the patch) and they stay in that area. Additionally, this was new for me, there is another spawn point BEFORE the big doors to the right, Captains and Vandals were coming out of there and chasing us back down the stairs. At one point they chased us so far down that Sepiks recovered all his health. Then sometimes both those captains would rush me at the same time with their Vandals for some insta-death fun. That strike took us 1.5hrs. Main strategy was LPERKO at level 27 was the rear guard, Bach3000 looking out for the spawn before the big doors, then me doing the hero sniping Sepiks. For that effort I got a leg fusion (I don't use fusions) and Bach3000 got the Ice Breaker which was rather nice for him :) Seemed much harder than it should have been, so I thought it must be a bad camping spot now. Interesting reading your experiences.
