If we nail the Davy, we could use a Revision to copy it into a smaller, similar version, weaker, with more focus on distance and aiming...
You know, the Swizzler, just made a little differently. Like, a pre-loaded Ink Tank or something.
I mean, I'm not sure that would actually be possible, we definitely wouldn't be able to make it go a
greater distance without changing the entire mechanism with which it works because the entire reason why the Davy Jones can travel so far in the first place is because it contains a level of ink and physics defying cephalopod power that can
only be achieve with a special. Without the ink energy, all the ink being pumped into it would likely cause the projectile to launch prematurely if it's not actively held in place by something, and attempting to get that range using pure ink-pressure alone would lead to absolutely horrid ink efficiency. If we made a scaled down Davy Jones as a primary weapon, it would more than likely be a grenade launcher
if it even works at all, most likely
never a long range weapon(it would be pitifully weak at long ranges in fact, if it explodes at all at that distance since the pressure is just so low), unless we develop actual real world style rocket propulsion at least.
There's also the fact that it would be a primary weapon with limited ammunition, whereas any other weapon you can just dive into the ink and refill your tank, the Davy Jones uses solid projectiles that are
filled with ink. So you can only have so many shots before you have to go and find more ammunition, which gives it an innate disadvantage against literally ALL regular ink weaponry, and honestly might wind up making it get classed as a sub-weapon. The current Davy Jones can get away with it by being a special so you can only use it very occasionally, but a primary weapon is meant to be used as, well, your
primary source of damage.
