My rotation with overheat WF starts with flamethrower to go overheat.

My rotation with normal WF also include flamethrower as an oGCD.

But since flamethrower is kinda clunky to use and it doesn't seem to be parsed correctly atm, I can't tell if it does damage in fight. A reminder that if you're going to use it as an oGCD, your heat at the start of WF shouldn't be higher than 75. Or you'll go overheat at the end of WF, and it is likely that BS is down, which is a big lost to potency (~10 GCD with 30 lower potency each, not able to use ~5 ammo, that is ~425 potency lost).

Also rook overload seriously need a buff. It is straight out a potency lost even under hypercharge and it crit during WF:

turret up for 30s: 80*10=800
crit overload with WF: 400*1.5*1.25*1.05=787.5

Unless combined with like trick attack, the balance, other 5% damage buff, it is still only ~200 higher, and that is when it crit. If it doesn't crit, it is a potency lost no matter what.
