@1ronKeys Agreed.. That's not to say you can't make some weapons work in ranges they were not intended for. I do it all the time when I come across lower skilled players. I'll pull out my longbow and use it in CQC against them.
One thing I have noticed, Pathfinders seem to love running duel CQC load outs. I think they do this because of the grapple. It's really easy for them to close the gap and make almost every fight they get into a CQC engagement. I actually target the pathfinders first now. Sooner they are out of the fight the better.
I'm on the fence about the R-99 needing a nerf. I have been melted by it at range by highly skilled players. I had a G7 or R-301 and should have had the advantage with the distance involved. But the top players have become so adept at recoil control, that they can fire the R-99 as though it has no recoil. Thus using it at ranges that the R-99 should be ineffective. But does that mean the gun needs a nerf? I'm not so sure, I'm fairly confident they still would have won the fight no matter what gun they had.
