If you have 10k+ dps on the log after dhuum thats usually fine for a normal pug imo.
As shortbow soulbeast you can prolly get up to like 12-13k i would guess, but ill try it today to get some numbers.
Problem with dhuum is that depending on mechanics your dps can fluctuate quite a bit (Getting a lot of bombs/shackles) + in inexperienced groups or groups that play bad comps on dhuum your boons might be lacking and youre gonna lose some dps aswell.
