the utter un-importance of rank is what makes AH so fun - no death penalty, no grind, no real ranks that give any benifits = pure pvp win.
which is why peopl who run from fights nevr really made sense to me - so what if you get ganked - one in ten times (or more if you have skillz) you can reverse and pull some amazing wins - which gives me incentive to fight no matter what the odds - unless there is a larger picture.
at least thats how I see it
