Your first problem is Night Elves. Kill them all. Then we can talk.
The Alliance are all bloody little girls. For the horde!!
Nah, Gnomes and Dwarves are cool, and once they get Draenei they'll actually be a worthwhile faction. Both sides with have three awesome races; Trolls, Orcs, and Tauren vs. Dwarves, Gnomes, and Draenei.
The people I've met who play Alliance are all sore losers and annoying, obnoxious individuals. I once started a Night Elf to see what it was like, and I'm flamed about 5 times for all these odd and unfitting reasons. The horde is more lively and fun. Especially The Barrens chat. ;-)
