Who is your favorite character on the opposing faction?
Write down your faction, and who you like.
A few rules.
Choose someone you would like on your side. Don't put something like "I'm Alliance, and I like Garrosh because now the Horde is led by Warchief Herp-A-Derp."
No Neutral Heroes
This includes Tirion, Thrall, Rhonin, Malfurion, etc.
If you aren't sure if a character is a neutral hero, write them down anyway, and then write your second choice as well, just in case.
Personally, I am Horde, and I like Muradin Bronzebeard.
Edit: Doesn't have to be ingame character.
Edit2: There has been question about whether Bolvar is Alliance or Neutral Hero. For purposes of this thread, he counts as Alliance.
