Something like a month ago, so before 5.4.7. I have some recordings, so, I will check what's going wrong. Idea was to kill Anshal first with a DoT timing from ToK (so he dies something like 1 second after the invocation of the little plants) before going on the two other plateforms and switching between Nezir and Rohash. Anyway, I probably won't have enough will to slain this boss regarding the absence of interest. Other boss deserve more attention, imo (Oh yeah...).
Also, as you say, even with the bug, it's likely not to be doable so... why persisting ? Btw, well done for the down with the druid
