So like. Vorpal is really good on single-hit weapons. It's perfect to get occasionally on a crit because like "WOWWEE THAT WAS AWESOME!"

Then you look at something like Autopistol Akimbo that can fire 6 shots for 3 momentum, off-hand shot for 3 M and 6 more shots, and you'll probably have enough momentum to move away or WRECK-ASS JPEG if you're a kensei because you just got 11 momentum in total for that turn if you critted atleast once with both weapons < Which isn't that hard >.

For this akimbo gunner that already ignores defense, each vorpal strike just got an extra ENEMY DEF to them. Creating unbalanced gameplay by sometimes giving their already powerful crits 1.5x Damage and +40 ( enemy defense) damage ontop of that. While for single shot rifles/shotguns, this is semi-fair since for the most part they won't proc it very often due to low vorpal chance.

The Pistol MGs, once again, come out top dog in DPS due to their ability to fire multiple... multiple shots and get the basic shell bonus numerous times < which can get powerful on is own right: See Null Shell/Interference Shell.

Could this be dropped down on multi-shot guns, or simply nerfed to some degree to make it permissible with 18+ basic attacks a turn?

Guns, aside from multi-shooters, are fine as-is with Vorpal because it procs so rarely and generally speaking, the damage is negligible to some degree compared to some people pulling 150 damage crits out of their ass compared to a perfect SKI snipers 90.
