In challenge mode, adds do not despawn when new adds spawn. If you fail to kill them all, you will be tanking multiple groups of adds.
Not really, the best thing to do is JUST cure healers and tanks and leave it on the rest of the raid. The curse is too frequent and not worth curing everyone. Just worry about curing Tanks and Healers, its just something you have to deal with.
I didnt see it in the strat anywhere and may be too irrelavent to mention or cloud the strat with, but there is a curse or two, 1 turns you into a ghost and nearby allies suffer severe power drains, sometimes you cannot move away as the ghost, maybe bad timing with the AE stun, but if the ghost cant move the raid should, or is there an easier way to avoid that aspect of the fight?
CM updated, not really any different than EM.
I'm pretty sure there are three possible places where the cloud spawns, depending on certain conditions. I've been watching it and have noticed the following pattern:
1. The cloud will appear where it dies.
2. If an cloud already exists where another mob dies, then the orb will appear on the person who got the killshot. The clouds can't intersect.
3. If the person that got the killshot is in a cloud already (ex. tank that hasn't moved out of a cloud), then the cloud will appear on the named.
