Corinth uses 3 ammo on its alt-fire

[(XBOX)The Mad Combat]

When the Corinth shotgun released, its alt-fire used one ammo per shot, thus 5 uses before a reload with the standard mag size of 5. This was then somehow changed to 3 ammo use per shot? I cant track down when this was changed, cause it never seemed to get into a patch note. Likely it was changed after Corinth Prime was introduced, but it makes no sense from a balance standpoint. Corinth Prime does 4 times the damage and a bigger radius (only 10% bigger) than the non prime version, so having the regular Corinth use 3 ammo per Alt-Fire seems to be an unneeded nerf.

 

This happens in the current version of the game.
