We killed Fathom Lord Karathress last night. Two new bosses in a week. Hopefully this is a sign that we are out of our slump.
I have mixed feelings about this kill. We killed him on the ninth try. On the first seven tries, I was Prot-specced and tanking the priest. On the eight try, I tanked the hunter, but the dps pulled him off me. So one of our warriors, who was DPS, and I teleported to Ironforge. He respecced Prot, I respecced Holy, and we came back in and killed Karathress.
It's probable that having that ninth healer was what put us over the edge, especially for keeping the raid alive (Karathress randomly Bolts a raid member for 50% of their max health), rather than having a warrior tank instead of me. But still, in some ways I kind of feel that I failed as a tank.
The respec was probably unnecessary, as I finished the fight with like 60% mana, so I probably could have healed it as Protection wearing Holy gear. However, it was frustrating after eight tries, so we made sure.
