GMs only use there armor in beta testing for they dont have to lvl so slowly due to they have to get to lvl 75 in the beta testing to make sure its possible.
a GM is a game master. They are sort of like moderators or administrators, they help people, or at least try, and also take care of 90% of the idiots you don't see many of.
Because the GM gear has godly defense and if they released it to players we'd be too strong. Just because you want to be able to smash everything in one doesn't mean you can.
i wonder what theys earnigs look like? i wouldent be suprised if they were just kite sheilds that you hang from you ears.... that would hurt but be worth it!
