Yesterday my buddy in the BIGGUILD was talking about these War Scout thingies - I still can't get my mage Ceniza over the tipping point of gear score, no matter what I do, no matter...what...I....do....(can you spell "white whale?") In any case, these bad asses drop rep points and other goodies. Be warned: they hit hard. Take a friend.
Pro tip: Don't let your hunter buddy get in PvP fight right before a Scout fight: the Blood Elf whateverthehellhewas stays angry for awhile, and will kill you while you're trying to shield your pretty face from the big, mean troll.
