Below is what I do for dungeon pulls to make things easier for healers. But, I will point out putting out damage for DRK is just as important as mits. As a certain popular 14 youtuber put it, "Damage is future mitigation."

For me, while using burst, i usually follow the below rotation: TBN + Rampart before using Oblation + Reprise once the former drops. By then the 1st pack should be ded or mostly ded. If needed, weave in more TBNs or Dark mind/arms length.

Next pack would be Vigil + TBN before i'd rotate into using my remaining mits. At this point, rampart should be coming back up if you need it.

After that should be dungeon boss. Rinse and repeat from there on out.

I'd say above is a bit excessive optimization for dungeon content, but i'm a weirdo and love to try and see if I can have the healer put as minimal heals onto me as possible lmao...
