Personally, i hate Alliance.....little fricking gnomes. Plus why the heck would you make a gnome or dwarf? Also Alliance looks to Human like...Horde on the other hand has more beast-like appearances and more Shammys.=P

If you dont like Horde then try Alliance but i'm warning you..it really sucks.  A few more reasons is because Alliance is for younger people cuz they're scared of the Horde and they just like they Munchkins in the Wizard of Oz.
