we run 10m raid guild and I find it hard to estimate/measure expected raid dps. I have only gear and simcraft simulations that tell me "this guy should do 100k dps with minor movement" and my logs tell me always the difference (about 5%-10%). I find it hard to interpret this "movement variations" in simcraft. How do I know if my damage dealers are pushing to limit or if there is a lot of room improvement?
Most common and very time consuming method for me is to find a similar equiped character and try to find logs for the same boss and try to compare both. After that I can see e.i more dot uptime or higher activity time, better cooldown usage.
What is your way to be sure that your DPS is doing good job?
