Did the Fp yesterday with assasin-tank, 2 arsenal bh´s and a sorc healer.
Tank had to interrupt incinerate, but if he caught on or two stacks of debuff, he had to be decursed immidiately. The tank even survided an incinerate, that got through, cause we spammed decurse in a row on him (he dropped to 0%hp, but still alive^^)
Wiped 5 or 6 times, till we got the mechanics right.
The other boss, who jumps on his towers and shoots you with poison, was much harder, cause he obviusly bugged the first few times and changed his tower like every 3 seconds^^ The try we got him, hin stayed on on tower for like 10seconds, so you could actually burn him off, which seems to me more working as intended then the 3second version does
