Admittedly I saw your numbers. Nothing much to say, that's for sure. People are too conscious on the dps when the real issue is on the skill, the deviation is too wide apart even when your tank stance is a constant.For example, can you tell how I would end on the DPS scale ?
On the topic of turtle tank, I have to emphasize again that turtle tank doesn't exist in this game and I very much doubt there will ever be one, so long as healers are still a huge factor.
