Nice Vid! Noticed you applied SW:P before 5 stacks of Shadow Weaving buff or whatever its called. Always get 5 stacks before you apply SWP as you're missing out on 2% dmg from it all fight otherwise.
SW:P refreshing the dmg every mind flay. So it what ever when you cast apply the dot. Some ppl cast Inner Focus for SW:P but its like maybe for first tick ... then the crit is gone because it refreshing every time with current SP
