Yet I was still surprised to discover that one of my relatively new friends had actually defected from the Horde to the Alliance. As a roleplayer, apparently he felt that the Horde roleplayers kept on rehashing the same roleplay material, about death, trollish accents, and "strength and honor." I admit that my experience with my Horde hasn't been so in-depth, but so far I'm thoroughly enjoying my Horde characters, and I haven't had the same problem at all. In fact, it's my (limited) experience that Horde tend to complain least about their faction, in the same way that warlocks complain least about their class, though not at all with the same consistency.
Have you or someone you've known ever left the Horde and made new Alliance main characters? If so, why?
