You want full speed running while drinking back? Thats dumb. You go run and drink at the same time, I'm sure that will work out great. Can we get a wet undergarments debuff that causes a chafing wound?
Sure +1 to legacy combat, but I don't see how full speed running while chugging is a requirement for you. Theres more strategy involved with slowed drinking, and if we all experience that slowdown why would full running change much at all anyways?
