Recently I have been trying to give SLR's on the recon class a go, and it's been a frustrating time.
At one end of the spectrum you have the Semi Auto rifles on Assault and the Bolt Action rifles for Recon at the other end, the recon's SLR's excel at nothing in comparison. 2 shots the head, and (the majority of the time) 3 shots to the body, this wouldn't be a problem if they didn't have the enormous recoil. The amount of ammo you start with doesn't help either. 25 bullets!? At least with Bolt Actions you can deal a significant amount of damage with that amount but with SLR's, you use it up in no time.
I wouldn't want a change in how many shots to the head it takes, this would make the Bolt Action rifles completely redundant if it only took 1 shot, but at least a guarantee that 2 shots to the torso can take an enemy down would be nice. This would also fix the lack of ammo problem.
I just feel as the semi auto rifles on the assault class kill with as many shots, with a much faster rate of fire, and noticeably less recoil. Taking away all incentive to use the SLR's.
