When I received the first order of WOW t shirts, I realized this is one category where my personal bias is going to get me into trouble. Essentially I only ordered Horde t shirts and no Alliance (although technically the Three Worgen shirt would qualify as Alliance once Cataclysm comes out). I guess that's what comes of playing vanilla WOW on a PvP server. You don't know what PvP hell is until you have had to level through STV with bored 60's beating your ass all day.
Next time I will order some Alliance shirts, although it galls me intensely. I wonder if they do Alliance shirts in children's sizes...
