I'll admit it: I'm a gnome-aholic. If I had my way, every single one of my characters would be a gnome. My warlock? Originally a gnome. My rogue? Also used to be a gnome. My hunter? Sometimes I dream at night of a gnome, pink pigtails bouncing, as she charges into battle riding her devilsaur pet. They're just so cute!
That said, since moving in with my current roommates, I've found that there is no way I can express my gnome love. Both of my roomies are die-hard Hordies, and in order to play together with them, I've had to transfer all of my beloved gnomes into not-so-beloved Horde equivalents. Not that there's nothing to love in the Horde (I would marry a troll and adore goblins!), but sometimes when I'm in a battleground and I see a gnome charging, I ... I just can't find it in my heart to melt his/her adorable face off.
Sometimes I fantasize about transferring all of my characters back to the Alliance and making them all gnomes again or making myself a secret gnome toon. However, I've realized that I would miss playing with my friends too much. Sure, if I rolled a gnome, I would still be able to talk to them, but I wouldn't be able to run a few random heroics with them, pop into Silvermoon for some RP or ask them to run my level 23 alt through a dungeon so I can get all the loots for myself.
So what about you? Have you ever rolled a certain race or class in order to fit in with your friends?
