Following up on that post though, there's another problem in that MCH's DPS weighs so heavily on good wildfires already that buffing it like that could be a huge deal when it's already pretty well balanced with BRD.
I would like it though if you could at least trigger wildfire again to make it go off at whatever timing it's at. You could do something like dump all your big OGCDs right before a boss jumps for a decent amount of damage without having to worry about your skill timings too much.
