Nothing stops members of the LF Guilds to play PvP, especially since, as Lynk pointed at, we've moved to The Harbinger. The LF Guilds are primarily a casual PvE guild and as far as I'm concerned, that's the way it should be. But that doesn't mean we can't try to organize some PvP matches sometimes, in the same vein as we organize World Boss killings or Datacron hunting (we really should start one of those some time
). The only problem would be having enough members to do so, other than that, I'm all for it.
