I'm not sure if you guys know this youtube channel / Website, but I had to share it. It has plenty of animations about WoW and they are very funny because they usually are based on exactly class related stuff, from Vanilla raids/dungeons, PvP, using their class spells, leveling in Burning Crusade, building the team for Karazhan and an endless etc. And equal on Alliance/Horde characters.
I was having so much fun that I wanted to share it. The cartoony characters designs are awesome and I already have my fave one, the undead rogue girl. The Taurens characters are really funny.
Take a look and watch any of their stories. All of them have subtitles. And I'm sorry in advance is this was already posted.
Youtube channel with lot of videos:
