Whether or not you think your DPS is important or not is not in question. Because it IS important. If your monk could boost his DPS by 10, would you not expect him to? Also, Mijin you contradict yourself when you say that SS is better for using defensive/threat generating skills, and continue to say 'there is only so much threat you need to generate...'

A less experienced tank should realize when he is wrong, and just take the advice from people more experienced than himself.
