You are right that my 1k dps doesn't include devilment but that is a very difficult buff to napkin math calculate the avg contribution of since its not a flat increase but a chance to do extra damage which obviously has diminishing returns based on your partners gear and skill.
Devilment is already accounted for in your personal dps numbers. It has the same uptime as technical finish with is around 16.6667% so for arugment sake lets say devilment has equal dps contributions to your partner as technical step which is basically 1% extra damage. So instead of giving the BLM 5% you are now giving him 6% not including technical step (that was calculated from party dps). BLM's portion of dps that belongs to the DNC is now 642 dps instead of 535. So an extra 100 dps. This would bring DNC raid contribution to an average of 1.1k dps vs the original 1k. This puts AVG DNC total dps at 9300 dps based on 75th percentile parses which still leaves it in the bottom 3 dps.
All I'm getting at is that the disparity between DNC, BRD and MCH is much higher than what the buffs account for. There is currently a 2k dps gap between MCH and DNC. No matter how you swing it, Devilment will not end up being an extra 1k dps to close the gap between them. I'm playing DNC because I enjoy the style of play and will continue to do so. But with current tuning, the reason why dancers are liked is because they help BLMs and SAMS get high parses, not because their total contribution to raid dps is more than another ranged dps.
If you only care about damage and can't wait for tuning passes, you should play MCH. Otherwise, DNC is a very satisfying and fun class. If people won't take you as a dancer because of week 2 tuning, then you need to find new people because while DNC is under-tuned, it is no where near nonviable considering all of the logs are from successful kills in which there are more DNC parses than any other class.
My post isn't to complain about DNC but to bring awareness to realistic current state of things rather than have it buried under "I mean your a buff class, you probably add like 4k dps to raid from it. Stop complaining". We need some love and I hope we get it considering its my Main Job and I'm here to stay.
