Well we know that worgens dont get a mount, they get a spell so they run like a wild beast.
Today i did a quest on my dk in Grizzly Hills, [Escape from Silverbrook] were you have to jump on a hours and run from some worgens, they do in fact jump down on all 4 and run like a beast do you think blizzard are going to use the same annimation or simmilar to that one ?
(sorry for bad spelling and gramma) hope you can understand it and read it
