I know the video is long, but it is well worth the download. This is the first and only video of its kind. I have recorded PvP moments with my dual weild fury build since lvl 30. I have compiled my best moments into one video. I gurantee you have never seen anything like this before.
The video also shows the increase of the ability and damage of fury. Fury was broken for a long time, because heroic strike would stop your offhand from swinging while pressing heroic strike and waiting on your mainhand weapon timer. By the end, you can see the full power of fury.
Area One Lowbie: Broken heroic strike
Area Two Dal Rends: Fixed heroic strike
Area Three PvP gear: Old Bloodthirst
Area Four: Enrage Buff / New Bloodthirst.
So download the movie then go grab some food, walk out side, take a bathroom break and it will be done when you get back :)
I can answer most of your questions here
NOTE the bug where when I charge and immediatly change stances, you do not see the dmg output above their head, yet damage is taken.
