Looks like you're kind of getting your wish although not with FoV itself.
Suggested Changes toward Fang of Vog
I want to suggest a real suggestion toward fang of vog in my personal opinion.
1) Decrease the damage of fire burning
or
2) Decrease the duration of fire burning time regardless of having fire resistant uv on armor or having fire resistant armor
or
3) Maybe just remove the self-inflict burning and nerf the damage a bit to make the sword balanced
I'd like to see Fang of Vog changed into an elemental cutter tbh.
Keep the charge swing but make the standard attack a fire cutter.
I agree with Disgr-Ace's suggestion of making FoV the "elemental cutter," while also keeping its spinning charge attack.
This would preserve the most iconic functionality of the weapon (its charge attack), while also salvaging its worst aspect (its atrociously slow and unfun basic attacks). It should also be fairly simple to implement.
I would also just outright remove the chance the inflict self-fire, while we're adjusting the weapon. Self-status is extremely punishing, and FoV's charge attack isn't anywhere near powerful enough to justify turning it into a pseudo-suicide button. It's one of those things that's sort of cool thematically but ultimately just an excessive handicap in practice.
