Hmm, mostly thinking about AK, since thats what I've been doing the most of.

Generally, with a lower geared tank if you kill the first out of the tri-pack pulls its much easier for the healer to heal them up, esp if they again are lowered geared, so have worse AoE threat.

I never even thought about using miasma 2 for packs, it didn't seem worthwhile, and Tri-disaster is also a dps loss on 3 targets so i usually tridot contagion, shadowflare bane, then tab thunder and spam ruin.

I've had healers also spam Holy when the tank is well geared, so trash packs just melt.

EDIT: guess I will try miasma2 + contagion for add packs.
