pures will by no means be useless, they just wont be effective against non pures. Armor has health boosting properties so pures are gunna have a hell of a lot more to chip away at if they try to take on an account with any defense advantage. Also pures will not be able to find fights with people with def anyways unless they are really low level due to the way the combat level is going to be calculated (def lvl+2+the highest lvl out of atk, str, mage and range=combat for a maximum of 200) meaning a mage pure with 1 def and 99 mage would come out to lvl 102 considering most mages alch their way to 99 leaving their hp already lacking they will be killed fairly easily so i would suggest getting your atk str and range to 99 or atleast fairly high as it wouldnt effect your cbt lvl whatsoever. I however dont think this cbt lvl formula is going to stick at all...it makes no sense 2 99's shows as maxed and prayer as well as summoning arent even in the equation.. thats simply ridiculous and im sure with all the bitching surrounding it that it will be reconsidered.
