God damn i was in the middle of typing this - "Cabal raid boss could include some boss that you have to trick into being in a certain location at certain times via some mechanics so that auto turrets shoot off pieces of his armor that then become temporary damage zones. In between damage phases you'd have to dodge fire from said auto turrets and the obvious waves of enemies and the like." and then I looked down two posts and saw your reply. Well.....shit. Hah.
