I don't think you're getting it. Maybe you haven't actually looked at what the buffs are. GBoW is a health and mana regen. Do you put it on a tank or healer? GBoK is an absorb shield. Which tank gets it? You're probably not going to have more than one Ret, but you might decide to take more BECAUSE of their buffs. The idea that it's basically the same amount of complexity as an automatic raid buff is dumb.
