I like snipering, though I don't do it often. On BF:V, On Operation Irving I decided to have a go snipering, because in the Americans homebase all most of them do is stand there for ages whilst another helicopter spawns (which only holds two people
) I had fun snipering a lot of them down.
On BF:V you can't tell where the shot comes from, but whenever you die, the camera moves up and watches the person who shot you, so whenm you respawn you can go kill the sniper. Nobody killed me however, and by bullets ran out. It's about a ten minute walk back to base, so I just tried to steal a helicopter
*goes and plays BF:V*
EDIT: Anywho, I don't think it's cowardly and evil at all, just rather annoying if you're the victim and you don't know where your enemy is.
