Since the fall of the Bastion of Twilight, Yor'sahj the Unsleeping has eagerly assisted Deathwing, providing the Destroyer with the means to release more faceless ones from their prisons deep beneath the earth. Their numbers are endless and their power is beyond reckoning, and Yor'sahj intends to reap a grim reward for his faithful service. Five different kinds of blobs (I think) and you can kill one as four move in, the result is a different combination of abilities that require different responses. Sometimes you have to stand on each other, sometimes you have to spread out. Its like a goddamn minefield for the soul.
