I was running Epic Tharashk Arena a few days ago, and in the arena fight I was surprised to see red-named mobs apearing in each of the various waves. I haven't run the quest in a while, but I feel quite sure that in previous runs the only red named enemies I saw were Deadheart and his little buddy. Is this a recent-ish change, or is my memory just faulty.
I'll note that the red named trash mobs were all spellcasters - Mudwallow Ogre Mage, Horns of Fury Shaman, etc. My hunch is that this was just a quick way to increase "difficulty", by making the only enemies that posed any kind of threat immune to insta-kills and incapacitation. Has anyone run this enough to confirm this - either that it was a change, or that I'm totally offbase and need to get my memory checked?
