Downvoted simply because you proved no argument besides being annoyed. When you could do something simply as use medkits. And maybe you should work on your aim if the current med kit system is making it hard to kill. I have 0 problems when fighting people who use them constantly, although they are harder to kill, but that makes it challenging. So, basically a translation of this suggestion is "Sometimes I can't get my kill arrest, due to lack of aim, so now med kits are being abused".
Well my suggestion is simple. I like the new medkit system, but every time I try to kill a criminal, he is using his medkits to heal then "pwn's" us. Its getting annoying, but criminals have abused the medkit update since day 1. I really would like it if when a cop starts shooting a criminal, make it to where they can't get medkit healed until 10 seconds have passed. /discuss
