Taunts seem to be broken the the lastest version of omen it seems. They do not put the threat of the person who taunted at the correct threat. Makes Brut. VERY interesting..... Here is a combat log if anyone can solve it.
Tanks: Powershift (Druid) shags (warrior)
Shags get starting aggro and then druid taunts off him and it goes back and forth as the fight progresses. This was a failed attempt so the log is short.
