hp washing after the kms patch

You know, there is a chance/risk that they will put every character down to a standard HP. They probably will not factor in HP washing, because that is a glitch and they can always claim that if you take advantage, you do so at your own risk. I can't really see any other option unless they want to permanently screw the high leveled folks that did not wash. They would end up with way less HP if the HP gain per level is changed with the new system.
