Are you only interested in grouping or raids too?
If you like raiding check out The Faceless Ordr at

We're a progression raiding guild on Test Server and currently in Luclin Era (level 60 raid force). We have a large number of returning players in guild and currently pull around 36 for raids. Lots of groups and players willing to help you gear up, level, AA, quest, etc when we're not raiding.
Drop by Test and shoot me (Sebbi) a tell if you've got any questions.
