I use to play barbarian female characters and I tried recently playing a male one.

When affected by the nightmare affix he always ran (HC character dead by another bug see: http://us.battle.net/d3/en/forum/topic/7764346841 ) at 2 or maybe 3 times the normal running speed, making the character fleeing almort 2 screens away from the fight.

I played several female barbarians and the nightmare affix never caused such an escape (stuff and running speed bonus were comparable).

I also noticed that the whirlwind animation was much faster on that male barbarian than on any other female barbarian I played - and the ones I still play with. It may be somehow linked.
