Hey fellow forum-goers!
With all these new so called "badasses" coming into WoW, I thought I'd look into them and put them into and order of badass-ness that I thought was right:
1. Varok Saurfang - Always has been and always will be the reigning badass. Not only is he amazing in-game, but I love his lore and character development.
2. Therudin the Lost - He punched Deathwing in the face, and I totally believed him. One badass dwarf right there. No proper lore, but come on, face punch!
3. Thrall - He's holding Azeroth together all by himself at the Maelstrom (I think). Possibly the greatest Shaman in existence, and I like his lore xD
4. ROCK ON, And A Dinosaur, Epicus Maximus - Frickin' lazerbeams! (The undead on a devilsaur on a shark with lazorz that is patrolling the Maelstrom!)
5. Bolvar Fordragon - Withstood torture from the Lich King and took on the massive burden of becoming the new Lich King.
6. Crowley - To me he isn't much of a badass yet but it seems like there is a large fan-following for him, so meh!
Please feel free to comment on the order, but not with "OMG CROWLEY IS TOP, HE CAN CLEAVE WITH HIS FISTS!!!1!!!1!!!ONE!!!ELEVEN". I am not biased, I play both Alliance and Horde and like both about equally.
Mention any badasses and their achievements and I'll be sure to add them to my list after I've looked into them!
Lets keep the raging fanboyism flaming to a low please!
