The first boss is next to impossible. I would say impossible but you found a way to do it. I tried for 2hrs and cannot get past the first lever phase without dying. My gear level is in the 330+ range and heroics are so freaking hard its not even funny. Some trash hits so hard I can cc two of them and still struggle to keep my tank alive spamming greater heal. There is nothing fun about this. Yesterday it took me 5hrs to finish Heroic SFK. Thats just silly.
