Set myself up an L15, thermal scope class. Dam sniping is easy on this game. Even quick scoped quite a few poor souls.
Re acquainted myself with my 0 button when I see anyone within 5 yards of me.
Take that extra few seconds to head bob over everything I can find before I move.
Dont hesitate to lay prone anywhere. People rarely look down.
Throw my IED in random places to "make someones day".
Funny I am not that good and by doing those few things I easily had a 2.5/1 ratio while playing a couple of hours today. I definitely prefer a faster pace but I really like this game and had to adapt or continue to struggle with scores that were even bad for my standards.
