So right now in the current game heavy armor only stops 2 guns, sheriff and guardian (you can go into a custom game with a friend and test it if you don't believe me.) 600 creds for only stopping 2 guns, you could buy util or other guns with 600 credits if you just used light armor. What if heavy armor stopped aim punch, it would stop SMGs and shotguns from shooting you once and making your crosshair shoot to the sky, and it would make sense for it to stop it because you are spending more. It just seems like its pointless to buy heavy armor at the moment. Courtesy to Vetreon for this idea.
