So, I was just trying to get a Sha kill on my lvl 100 paladin.
There was nobody else in the zone and nobody was joining the group I made except for hoppers. I decided to wait next to it for a lvl 110 to come along and kill it.
After 10 minutes of camping, an alliance monk finally showed up, and, I kid you not, destroyed Sha in two shots, before I even realized it was being attacked. This is beyond insane.
