As a SMN it is already hard to measure your actual dps due to pet and the DMG increase and reduction you provide via utility, but key things to remember
-apply make sure DOTs are always up for the 3 second tick
-use contagion with RS, INT pot and PPP when possible
-limit use of energy drain, you want to fester as much as possible
-if multi strong targets (correct me if wrong) DOTS+contagion then bane
-keep up the ruin spam, while using pet buff- also there is a glitch where if you use enkindle then move pet before they cast it, it wont go off.
