I thought everyone in this thread would appreciate this video chronicling Chosen's 16-man Nightmare Tanks experience. Those who've beaten it can relate, those who haven't tried it yet... this is what you have to look forward to. Enjoy.
(there's some strong language, this fight will evoke that.)
Oh, I will also say that I have a tremendous amount of respect for you guys, and really anyone who has cleared it on 16 man. Not just for the kill, but for the wipes. You stuck it out, didn't murder each other out of frustration, and came out of it with the humility and good humor to share the experience with the community as a whole. Most people just brag about their kill times and throw around screenshots as if they always one-shot every boss.
