After killing Kel'Thuzad we decided to go check out Tarragrue mythic since we had heard it was an easy encounter. It took a little while before we did the first pull to run around the map and change our Anima Powers to be what we wanted them to be. But once we were done with that we did two pulls where he didn't die, and a third pull where he did. It was pretty much a free kill, like we suspected. Sylvanas Next!
