actually a sniper isnt meant to be taking many shots. its the one shot that counts that makes all the difference. an effective sniper can do 2 things, one is killing a shit load of people, and the other is killing one key member. for example. im my teams sniper, and a few games back i was hiding in the junk area. a kid walked by, and i didnt shoot. then his other friend followed up behind him, and i still didnt fire. finally i see Theo following the 2 other guys who were inexperienced. i managed to take Theo out, rather than shooting at the 1st guy i see and exposing myself to the rest of the guys.
taking out one key guy can change the whole course of a game. so i think your a pretty decent sniper, but the ability to go auto when you need to would be nice. so either get an AEG to convert to a sniper like i did, or get yourself a nice SMG. that will help
