Ya, dragon runs and tiamat runs it happens all the time. Very annoying since you are focused on the fights and can't look back at what your guildies were arguing about. lol.
The control wizard just got the biggest nerf possible. In a mod or 2, I'm gonna be runnin around like those other cw's who never came across thefab's guide in the first place.
Might not be what's happening to you, but there is a ring that makes you draw aggro while moving. See if you have that equipped. Then only put it on when you feel like being a tank.
If the final quest is to complete an area dungeon, join someone else's group and let them open the door for you. It will finish the quest when you complete it. Not sure about the beards though, but I swear my tiefling girl's skin color is way more red than I intended it to be. As for the epic dungeons. Shame.
