I have around 60,000 sniper kills- but there are still a LOT of guys right here that are way better than me- Like Sonic said, the longer you are in scope, the more chance you have of getting hit by about any weapon.
I would like to expand that thought just a little, if I may... it might help, maybe not- it helps me
1. never ever stand in one spot longer than 1 second, if at all-
2a. quickly strafe side to side at the same time as lining up your target WITHOUT scope towards the center of your screen- only then should you pull scope. then, if all is right, you will already be on or close to your target, so you can scope, shoot, and get out of dodge as fast as you can. If you are way off, dont think that you HAVE to shoot- just unscope and keep moving
2b. once you learn the specific maps, you will learn the good and bad spots to snipe from... there are a few that you can sit in one good sniping spot in scope for a while. I do it every now and then when there is a particular enemy sniper or MG that goes consistently to the same spot, I try to change his/her mind about doing that
3. I have noticed many many times that people that come from CS:S to DoD rarely have a problem picking up the game. Its mostly getting used to the weapons. the recoil on the support weapon for either side is nasty, but you will learn to drag your mouse down when more than burst fire is needed
4. rifle class is much the same, but I move a LOT more as rifleman. constant strafing, just only pausing for a split second to get a round off. gotta mix up the strafing too- cant just evenly go back and forth left to right- throw a little zag when they think you will zig.
5. Rocket and MG (to me MG is boring- I hate sitting in one spot) are fun- assault has its uses. welcome aboard and have fun! ask anything!
