Are 400 Pull Kills Good Design?

On September 1 we took our first three pulls on Heroic Rag, to “see what he was all about”. On September 6, we started working the fight in earnest. We are now some odd 345ish pulls into the fight, and each additional night that we work on the fight a small part of my soul dies. I no longer have the energy to get angry when people make mistakes.
