Hardest Boss in the Game

So we have been trying to down H LK and get our "Bane of the Fallen King" titles because they are super cool but we have been having some trouble with the hardest boss in the game, which is probably not the one you are thinking of. I actually dont know how hard H LK is because we have been losing to the attendance boss for 2 weeks now. It seems like after we got our drakes, that the people who weren't part of our original group of about 6 or 7 have just stopped showing up. This sucks. Luckily we are still able to do most of the heroics with pugs and are currently trying to get someone who is interested his drake for 20k gold which we will partially split among the regulars so I guess that is alright.

Also I am almost done with my CC basics post but i have to put it together and i have been really busy and been having internet issues so I'll try to get that out soon as i think it could become a valuable resource.
