I was passing by to the portals, when I stumbled into an invisible wall..and cannot move so here goes:
go to Shattrath, and to the Alliance Battleground Masters, if you head straight to the Dwarf Women (Alterac valley BM) from a good distance (5-6 yards or so) run straight to her middle, and you'll keep moving in the same spot, try a few more times if didn't work! Dunno if repost
