The 'unwritten rule' for non-tank pulls in dungeons

[Awha]

Its not so.much about the wall to wall pull but how a dps can tank as well as any tank when in fact can they takes hits? sure but can they take them as well as a tank? No

Saying that tanks are the most unimportant roll is an outright lie. If you want faster dungeon runs a tank in fact will make it faster if they don't suck.

For large pulls yeah a tank is required but for single pulls a tank is not absolutely needed, sure without a tank it will require extra healing but as a tank I honestly feel next to useless only doing single pulls.
