What I'm proposing is you make buff botting more of a bitch to deter people from doing it and instead encourage them to actually bring the classes then have content remodeled around not constantly rolling with all the important buffs by default. Lowering buff duration while leaving SB intact would not be nearly as effective to this end and if you're soloing or two-boxing for anything other than cash at a point where having multiple SB buffs is a factor you're just wasting your time anyways.
