Level 41 now, I played a lot and practiced. I try to avoid HC server as much as possible. I think the game get more and more satisfiyng as you progress trough the unlocks.
Before I went to level 41 I only played with a AK-74 with a silencer attached, I tried to improve my close range combat skills and just drop the idea of fighting long range most of the time. And that worked. I now get a Higher kill ratio and the game is more enjoyable. I keep on getting Air strikes and Helicopter support, which I think I got once when I started playing. My grenade skills also improved a tad, which helps a lot.
The P90 is still amazing, if not ever more than before (Damn it's accurate with Steady aim). I unlocked the silencer in like 2 spammy games and that's definitively my playing style. Flanking with a silencer weapon. :tup:
