Anyone else experiencing fake inferno debuff's?
Oh yeah, I've seen this happening a few times while I was on my tank. I would ask the offtank to taunt so that I could walk away and drop my Inferno, but when the debuff expired, it would not show a circle on the ground, and you could safely stand there without taking damage. This happened at least three times on my tank but I am not sure if I have seen it on my healer as well.
It is probably a bug, but this not a bug that could wipe a raid. In general, always be prepared to move away when you get Inferno, and be happy when the Inferno was a fake debuff.
