As of right now, there is only 3 ways to get this buff: Shamans, Frost Deathknights, and Survival Hunters. If there's more casters than melee and you have 1 shaman, then he's dropping Wrath of Air.
My suggestion is to either decrease the power of this buff to 10%, and/or give it to more classes.
An idea would be to give a talent to rogues that causes their Slice and Dice to also grant 20% haste to party/raid.
Another idea would be to give a third shout to Warriors that grants 20% haste that shares cooldown and cannot be used with Battle and Commanding Shout.
Bringing back Swift Retribution for ret paladins is also a thought.
