I believe that there should be a massive drop off of damage at X range. Since hardcore mode makes the bullet drop off greater, it can be learned just like normal mode essentially making the changes null. If you cause the damage to begin dropping at say 60, then exponentially decrease it to a point at say 200 meters where bullets do virtually no damage, this will incentivize the officer to move their line closer. This could solve the camping problem better than increasing bullet drop ever could and could maybe even be integrated into normal mode on the pub servers, preventing riflemen from sitting back and sniping as many players complain about.
