Doubt we'd have a guild, too many characters on too many servers.
Right now I'm taking a break from WoW while waiting for BC. I just don't see the point in raiding for the moment, or leveling an alt. And PVK is soooooooo fun...
Most of the guys in my guild I know in person. I don't think they invite people they don't know.
While they wait for BC, most of the guys are PVPing with the double honor weekends and all. They farm honor for a weekend and get a lvl 60 pvp epic weapon/armor.
