Historically, Warcraft has been quite friendly to boxers.
But that can be said of Eve Online, Everquest I, Lord of the Rings Online, Rift, Star Wars, and Vanguard as well.
For a while there, they didn't want boxers in EQ II, but that is not the case any longer.
Boxing has been allowed in SOE games, virtually from the beginning... a good five years longer than Wow.

While Wow is no longer going to be my primary game, actually I doubt I'll play it again in any form, that's not saying the majority are moving to Rift.
The same argument can be made for making EQ I, EQ II, Eve, LotRO, or Vanguard the default forum.
Which game, besides Wow is going to have the most boxers, following the /Follow fiasco?
Will Wow, with a primarily PvE boxing community retain its' position as most boxed game?
