the rng system need a damn good overhaul. 1: to make sure you don't constantly get the same items again and again. 2: to make sure you don't get lower tier items than the raid you are running (normal raid gear in heroic raid need i say more for that). 3: to make sure the items you get are equal to or better than the items you currently have. 4: the amount of work you put in is equal to the items you get (those carried through are getting better items at the moment than those doing all the work) the lower your kills the lower your chance at higher items ect.
