Ok, so I know that with my DoTs I want to try and hit the sweet spot for Pandemic but what about Haunt? Does Pandemic affect Haunt? Should I be burning through my Soul Shards in order to keep Haunt up at all times and try to clip it to increase duration with Pandemic? Or should I be hoarding Soul Shards for when I have Bloodlust or Dark Soul: Misery up with trinket on use and pots?
I know that you should never have full Soul Shards so that you don't waste Shadow Trance procs, but I'm finding that if I keep Haunt up at close to 100% while I have Soul Shards at the start of the fight, that during the middle of the fight I tend to go a long time without any Soul Shards, impatiently waiting for Shadow Trance to proc. So what is the proper usage of Haunt?
