Why the horde is just a bunch of 12 year olds saying the alliance is a bunch of 12 year olds. Also all their stuff looks dirty
The Night Elves are natural-born wussy tree huggers that shout "KILL ME!".
Gnomes and Dwarves look like they can be taken advantage of.
Humans, eh. They're alright.
Draenai, they're alright. I'll hand 'em that.
Now lets look at the Horde.
Orcs, huge bad-ass muscle masses.
Tauren, huge bad-ass muscle masses with fur.
Troll, meh.
Undead, scary-awesome-looking magical living dead.
Blood Elves, Night Elves/Humans but less wussy or boring.
