Just lost a gun fight to a Support while I was using the Hellriegel, simply because of suppression. It makes the bullets spread when it shouldn't. It simply shouldn't. The gun is a chunk of metal and wood, it does not have feelings, it does not care whether it gets hurt, it does not get PTSD, it should not spread the bullets around. The character you are playing as should be the one being suppressed, not the gun. Remove the high bullet spread when suppressed but make it so the soldier shakes rather than the gun being the problem.
