MCH: How to fix flamethrower

[CKNovel]

Let's be clear; Flamethrower is an absolutely garbage ability. The fact that it is our Level 70 "capstone ability" is a complete insult.
But Flamethrower is more a symptom of the problem than an anything. Fixing Flamethrower / making MCH AOE slightly better won't suddenly fix the job; but it certainly is telling that this ability (which is almost universally agreed to be terrible) has been left in this state for so long.

We can spitball ideas all day (a FLAMETHROWER not generating HEAT? CMON), but it won't matter at all if SE is still stuck in their "there isn't much we can change with MCH / the job is basically complete" views that they sprouted during the Endwalker pre-release tour, despite the the consensus between pretty much all FFXIV regional communities.

Various ideas:

The Reaper Flamethrower
Make Flamethrower consume 50 heat for a Reaper like phase where your 1 2 3 are changed to "Flamethrower buttons".
You don't get possessed by an avatar, simply by the urge of using a bigger gun.

The Doom Flamethrower (Flame Belch)
Flamethrower is now utility, no damage and debuff ennemies in front of you.
You and every other player character attacking this ennemy will get a stackable shield.

The Barrel Stabilizer Flamethrower
Flamethrower is now 2 charges, don't need a target and grant 25 heat on use.
Bonus point, you can now remove Barrel Stabilizer and use it as a new animation for Reassemble.

The Flamethrower turret
Summons a turret that hover over your character. Everytime you attack an ennemy, the Flamethrower turret spew a cone of flames towards that ennemy.
Leaves after a certain number of GCDs.

Button Bloat Flamethrower (Don't do this)
Flamethrower now shares a cooldown with Air Anchor and is now a simple GCD in AoE.
Also remove Reassemble because button bloat I guess.

Yes, MCH is far from complete and I can't believe SQEX would actually say "We believe it's complete" while it's the most incomplete job with its tank rotation.
Wildfire is not engaging, Flamethrower is an emote with damages attached to it.
And thanks to that new Queen finisher, it's now even jankier.
