Well a few months/weeks ago we were getting 16+ on a Saturday and 10+ regularly in the week, but overnight they disappeared, I'll try and encourage more by going on around 1700 UK time and sit there for 20 minutes, Labob is right once people see four they join very quickly. The problem with sniping is when you're learning the good snipers (because they're good) pick you off easily, this puts a lot of people off, but I persevered and now I'm getting better and don't get killed so often, I've even won a couple. I personally find sniping to be one of the most challenging games, if you make the effort you get the results, and that includes changing your camouflage at the start, one of the reason newcomers get slaughtered. It is a real team game which most people don't realise, in game you can talk to your own team (other team can't hear until the end) and guide each other onto movement that you cannot see (and don't expect to see much) and the highest scoring snipers move around and don't camp, but that needs skill.
I'll get you started, after selecting your weapon the countdown begins, at the end of the countdown you have the chance to change your camouflage but must be done straight away, depending on the map the instructions are there, you then are invisible to the enemy for a period of time until you find a spot when your rifle comes up, if you find a spot early you can bring the rifle up early by pressing melee (delete on mine), V zooms in on scope F zooms out, unless you have those keys assigned to other things. You do not have to steady the gun, the bullet goes where the crosshairs are, keep an eye out over the next few days and I'll go through it with you, we can't talk though unless on same side.
