I was boosting my son's low level warrior in Scarlet monastery at the weekend. (no raf sadly).

I was moonkin and basically pulled the boss back to the starting corridor and aoe'd everything down.

However, they must have changed something in a recent patch, because about 30 seconds after I'd killed everything the lady boss came running in, ressed Mograine and I got to kill them both. (It used to be bugged before so you couldn't kill both bosses and get loot).

It doesn't make a huge difference, but at least if you are levelling a disenchanter it's some more mats from the blue drops.
