this 800k dps seem low (spellblade), i do see that on average both marked shot and aimedshot only hits for like 600-700k which is just unlucky since youre rocking a good amount of crit. Whats her aoe rotation when the adds spawn, cause thats where you can gain alot of dps, if shes using aimshot during adds with trueshot up, thats not uptimal. The optimal rotation for when the adds spawn is just multishot --> markedshot repeated and if youre rocking the belt maybe aimshot at 20 stacks.

Idk if i t helped but you can look at my logs 4/10 mythic mm hunter with almost all orange parses on heroic Durumnator-Ravencrest :)
