Currently, Shaman can continually "cast" Ascendance, Ascendance - Spell - World of Warcraft simply after shifting into Ghost Wolf. The buff goes up after you leave, even if the ability is on cooldown. The shaman doesnt even need to be level 87; my friend at 85 cast ghost wolf and got it. No idea if the shaman merely needs to have the ability to get into ghost wolf to exploit this, it'll have to be tested.
