Lurker's awesome. Get under the water when he takes a breath!! Oh, and put sheeper and a fearer on each of the 3 islands to cc the 2 adds on each island.
Have you done Hydross yet? He's harder IMO, difficult tanking rotation between phases and adds.
Leotheras and Karathress gave us fits, but now Vashj is just a pain. Vashj is almost like the hurdle Razorgore was.... just so many adds and so much to time right, and everyone has to be doing their thing. Good times.
