I would just like to point out that tanks do not control the pace of the dungeon; healers do. Tanks are supposed to only pull what a healer can heal through. The amount of hate they can hold effectively is secondary.

People forget what the main part of every role is though. The base aspect of every role is to make the lives of the other roles/people in the dungeon easier. Everything else is secondary. Before anyone starts telling me I'm wrong I want them to actually think about the roles and how they effect other players. All roles have a symbiotic relationship and all are important.
