This is the build. I was very skeptical at first but I looked at it more and it’s clear to me 2 dom 4 nightmare is better than 6 nightmare. 1 swiftness ring and you have 30 second downtime of dom after your second cast, so your first 4 minutes of dps are fully juiced. 2 dom gives 18% cdr and 10% damage. 6 nightmare only gives 15% cdr. If you do 2-4 minute test on trixion I hit 4.7 and at 6inutes it’s 4.5-4.6m. In a 14 minute fight, you have 85% uptime on dominion. When you have dominion up, you do 32% more damage. With 6 nightmare you do 17.6% more damage. So in a 14 minute fight you do 27% more damage with 2 dom and 17.6% more damage with 6 nightmare. Current encounters don’t last 14 minutes either, so 2 dom becomes more effective.
