You know. It felt good when we downed Malygos, and Sarth 2D. It even felt good when we cleared Naxx, but this is the first time I've had that awesome feeling you get when you do something special. I haven't felt this way since I downed Vashj.
Realistically it's not that hard. None of the 15 bosses put up huge road blocks and I think a lot of guilds could do all of them with out dying. The question is do you have the focus to do all 15 with out dying. One slip up and its done. You can't try it again for another week. One lag spike and it could be over. That is some major pressure especially when you get to the final boss and you have to worry about void zones, ice tombs and mana bombs.
Grats to Myraxa for organizing a great run. Grats to everyone that got the achievement with me: Tirma, Sidonie, Victus, Draxa, Sevrenwinter, Osmand, Collbey, & Chamia. Great job guys.
