Without doubt, best guns are SCAR-H, UMP-45, G36C and I have a sneaking suspision the P90 will be a monster. I have everything unlocked for SCAR-H and UMP-45, still working on G36C, I've been side tracked by jets. Those people have trouble with aiming, I did to and I play other battlefield games. Just keep with it, I'm sure you will get use to it, I did in a few hours.
