No. I don't want to ever hear the excuse of someone dying because they were using their "pve spec" like unholy wars. Also I think buff others have a place in the game but you need to nerf their magnitude, not the duration necessarily. If you were going to do it right, it would be a 15 second buff but MORE magnitude. That's how you raise the skill ceiling. Consolidation of buffs is key to making the lower duration wards useful.
