Using the priorities listed in SimCraft except for when I begin; Haunt > Curse of Agony > Unstable Affliction > Siphon Life > Nightfall Shadow Bolt > Drain Soul (<20% target hp) > Immolate > Shadow Bolt > Life Tap.

Just keep refreshing your dots and prioritize in that order. When haunt is getting close to it's full duration just refresh it, should be no problem getting it up every ~12 seconds unless your lag is unbearable. And yeah.. you won't be able to do any easy rotations anymore, but I just find it more of a challenge when the rotation changes all the time
