He is right that in this day in age, we should be allowed to remove what actions we don't want on our bar. Months from now a noobie will ask his friend "Cool i just unlocked Herp wat do i do with it?" and his friend will reply with "Oh just throw it at the bottom of your bar with Durr and Hurr."

Buuuuuuuuuut, maybe we won't have useless abilities after 1.20 and we'll actually use every single class trait/ability that was given to us. Maybe.
