Sniper bullet trail should be removed !

The point I'm trying to make is not about glint, or bullet trail, it's about having the right balance and availability of choice to the player.

You should be able to remove bullet trail by selecting specific ammo, but then there should be a downside to maintain the balance. That downside should be reduced damage so that you can only have a one hit kill on headshots with that ammo.

We don't need people camping the outer sides of the map who can beam people with one shot in the body from across the map and meanwhile remain completely undetected to me or my team. Scope glint is one part of detection, sound is another, but if suppressors are used and the sniper is positioned on the side of me or in my back I won't see the glint and then a tracer would be the only clue. As Chris_Hawkner​ correctly describes, if you land your shots you already have your reward by means of a kill. If you miss you should not be further rewarded by keep taking pot shots without revealing your position in some way.

If tracers is the best way to do this remains debatable, but there needs to be some kind of discouragement to keep people from camping the same spot without consequences.
