It's not really complex though. Let's assume that SS, LL, and UE all come off CD at the same time. I have a decision to make and a single instant in time to make it. My fire elemental totem just came off CD but Imperator will be spawning a new add in 10s. Should I save it or just use it immediately? Those are the decision points I'm talking about. Yeah they are not incredibly difficult decisions, but they are still there to get wrong. With the warlock I didn't really have any decisions to make. Maybe when to put havoc on CD, but that's about it.
