On HowToPriest they say the spells priority is like this:
#1 - DP with SOx3
#2 - MB on CD, especially DI procs
#3 - SW: D x2 below 20%
#4 - MF:I while DPx3 is up
#5 - SW:P / VT
#6 - Halo / Cascade
I'm wondering, as I see I'm about to cast my next MB to get 3 orbs, to cast DP to trigger MF:I, and I see my dots are about to die... do I wait to cast DP to cast dots, do I cast DP then do the dots, or just MB -> DP -> MF until it's empty, then redot?
