I'm sure that they will simplify down the Double Enshroud window leading into the next expansion. I hope that it doesn't happen prior to this, because it's probably the only interesting melee dps burst and actually requires a bit of thought around your DD buff management leading into it. Part of the puzzle is figuring out how to get in as much potency as you can out of it. It's good for players to struggle with it, as it will encourage them to stop blindly dismissing the job without having any understanding of how it actually works.

I've said this before, but you don't actually want additional uses of HM. It's potency isn't all that high, and outside of AoE situations, it's really just there for disengages and as a recovery technique to give you a dummy GCD in place of DD. You generally don't want to slot HM into Enshroud because it displaces a more important GCD, unless we start getting encounters with multiple adds.
