You're wasting massive amounts of gcd uptime by doing triple weaves, especially when it's with Flamethrower. Overheat fits 6 gcds while Wildfire only fits 5, so it makes sense to FT>gcd>WF because that minimizes gcd clipping without losing any potency in OH or WF. Your opener is very inefficient because of the triple weaves, unnecessary unheated shots and split shots in your WF window. If you don't have procs to spend in OHWF it's better to just spam Cooldown for higher average potency. Your Hypercharge is also too late to align well with Overload, raid buffs and later burst windows.
