For what burst? To push wildfire into a 500 potency attack? That's laughable when you consider the minute long cooldown. The overheat also isn't worth going into considering the MASSIVE potency damage loss. If it were, maybe we would see more than 100 parses that include machinist. The heat gauge as is, is literally a punishment device that does not reward good play but instead gates you from dealing normal damage. The incentive currently is that you either do it perfectly or your damage is going into the garbage.
