Last night I was teamed up with a pally buddy of mine. We were in The Rathe Mts. hunting Hill Giants. All was going well, with many successful kills and much celebrating.
We were finishing off a Giant, he was giving us very little problem. The pally was down to 52% health when the giant got down to 19%. but he didn't run. I spun around to see if there was an add that I had missed, but there was none. By the time I turned around the pally was dead. Dead in only 2 or 3 seconds. My pet and I finished off the giant who was now running with no problem.
I have never encountered a mob frenzying, but I guess this was it.
How and when does a mob frenzy, anyone know?
