I had a friend, he said i would get into it. Naturally i tried. I made an account named Lazzarus, Buffyou. Etc. On Aggamagan, alliance.
I then became a well known PVPer and changed my name. FrostShock Etc. The i rolled a paladin, that became a huge hit. An i got a team rating of over 2k in season 2 (which was the best) I then became Horde because i got into the game, i was hooked so i rolled Horde.
I do regret being ally but you just follow your friends, now i've seen the light.
