Do you use your abilities in a rotation or priority system for optimal performance? Can you describe, briefly, how it works? Why?
I use my abilities in priority system.
In short, keep the dot up, refresh shortly after it expires. Pop my CDs mostly when they are available, except for Soul Reaper(when low on runes), dump rune power with DC, keep my festering wounds stack low to avoid cap. Use AMS when able to get some addition rune power.
Why do you gear the way you do? Why do you have these items and enchants?
Haste and Versa sim the best for me. Crit is not far behind. Avoid mastery at all costs. Prioritize azerite armor with Festering might/undead magus/overwhelming power.
Benthic socketed items provide bonuses in EP that overshadow ilvl difference even of 445 ilvl gear.
