With the new recoil overhaul the Vermin suffered a heavily increased muzzle climb in all stances, which does not fit this weapon in my opinion.
The KRISS Vector is entirely designed around massively reducing muzzle climb, however the Vermin, which is the Arma equivalent of said weapon, suffers this issue as much as "usual" weapons do. Firing an entire magazine, the Vermin suffers around 1.5 times the amount of muzzle climb of e.g. the Sting, which is the opposite of what you would expect.

Instead there should be mostly an increased spray with increased duration of auto fire, while the muzzle climb should be reduced to a very small amount in comparison to other weapons.
