A giant frontal cleave and whirlwind that hits mail armor for ~2200. The cleave has a large depth to it (was hitting people far behind the warrior tanking it). They also will use sweeping strikes, which hit for melee damage as well (roughly 2200 on mail as well).
Simply position it facing away from the rest of the raid, like any normal mob that cleaves or has a frontal cone AE.
