I don't think I'm progressing slowly but yeah, I've always felt that scouts just feel fucking weird in this game on PC. Between most of the maps being tiny and the guns having zero recoil, they're easily the worst feeling guns I've ever played with in any FPS game. I just don't like them.
I actually perform the best with Jade Rabbit but I've been trying to use Black Scorpion because I prefer the automatic shots, makes it feel more like an auto. Also speaking of the Black Scorpion, body damage on that gun is pitiful. Makes my soul hurt when trying to hip fire to get a dude who's one shot and it does 17 damage leaving him with a sliver of health
