Well, that is no longer over in the regular Machinima stuff, You will have to learn to use Blender (Free) or 3DS Max/Maya (Free for Students) or even Cinema 4D, I am pretty sure CoW: Blind was made in Maya. There is a couple of tutorials at YouTube that are WoW Specific, and alot that are for general help for those programs, I would reccommend you to check out:
http://YouTube.com/thenewboston, he has alot of tutorials for modelling and animating, iirc.
