I've found a problem in this update(1.12). I was testing the new game balistic system, and found out that the stab vest can take 5 rounds of 9mm, and the ballistic only 4 rounds. When tested for the 556, both got 2 rounds, and the plate carrier 4. I think since the stab vest was supoused to be against only knifes and low caliber rounds, and the ballistic vest against mediun caliber rounds, doesnt make any sense the stab vest be better than the ballistic.
I believe that the vest system would be better if the balistic vest got a buff, and could suport not 2, but 3 rounds of 556. This way it would be more realistic and would improve the vest tier distribution. Ondering the vest tiers with my porpouse:
Tier 1- Stab vest/Tatical vest (5 shots of 9mm/2 shots of 556)
Tier 2- Ballistic vest (7 shots of 9mm/3 shots of 556)
Tier 3- Plate carrier vest (10 shotes of 9mm/4 shots of 556)
