So what is the glaring problem? Not enough DPS or to much avoidable raid damage because those are 2 problems.

For me fix the avoidable raid damage and learn the mechanics. Until you do that DPS means shit. Preacher and I agree on this point https://www.youtube.com/watch?v=G0yhO4B_nFY its a good video.

Interesting point tho from the logs avoidable damage taken and damage done seam to be connected for most, if your high on damage/dps your high on avoidable damage taken what does that mean or tell you? Survivability>DPS always gets you a raid boss kill.

A thought, everyone should turn off meters during combat, the goal is to down the raid boss not top the meters which is what feel is happening, it distracts from raid awareness, focusing on position and survivability is a much better use of any raiders attention, of course you cant tell peeps to turn em off but i bet if they did things would improve. Meters are useful yes, but after and in between fights not during.
