What if it were reworked so that Cooldown worked exactly as its name implies? Lessens Overheat uptime, or perhaps shortens the barrel cooling time (which I personally feel 10 seconds is a bit long anyways). This could serve to fast track us back to GB usage and minimize "downtime", giving our sustain a little help.

I actually like the Overheat mechanic, imperfect as it may currently be. It would seem our between burst or poor burst management penalties are too big right now, especially with overall uptime BRD has for all it does/can do. And while I still don't see that as doom for MCH, I'd simply say lessen the downtime, or increase the damage.

P.S. Cooldown needs a better name.
