Oh, I see. I misread the last bit.
But DoT management just for the sake of having something else to do wouldn't be that great really. Variant Spirit Dart is a button you can press in any weave window with no loss, meaning you can reapply it in advance if you are about to enter a period when all of your weave windows will be spoken for. If you actually had a DoT as part of your job action set, there would be a loss associated with applying it too early or too late, which would cause complaints when people get annoyed that they need to reapply their DoT early or late because it's going to fall off during a period of weave saturation.
