When I first tried to relearn MCH I noticed wildfire underperforming, in 4.0 it used to be unleash as many attacks as possible to gain that sweet 20-25k burst

After a few different approaches I found the most efficient method is to spam one move...

Not only that but if you dare to use any other move the Overheat slows to a odd crawl as if your supposed to use just one skill for the entirety of the wildfire buff, which is a oddly long Cooldown and of course it isn’t the best way, I have found a good mix, but man is it a massive far cry to the bombardment that was 4.0 Wildfire

Overheat should act as Old Rapid fire to all skills not just 2 one being Auto cross
