I guess it's kind of understandable. The 2/3/4 shot kills with the SVU in B:BC2 aren't all that bad. It takes a lot of skill to use the SVU, but it's so much more rewarding and versatile than the stupid bolt actions. Besides, wounding an enemy will actually mean something since they can't recover all the way without the help of a Medic. As for the leveling, it's supposed to be easy to start, and then you get thrown into a whole different dimension when you reach the next rank up.
I only use semi auto snipers in BBC2 but i can tell u it doesnt take too much skill to use them decently. the type88 can kill ppl in 2 shots easy and the SVU is 3 bullets. also the bolt actions i feel tak more skill to use but then again i sprint around the map when im sniping so the bolt actions arnt that helpful for me.
i personally think the LRs wont be as nerfed as we think they will be. i mean if we can drop a guy in 3/4 shots with the Drognav and 2 with the barret itll be a piece of cake, only ammo will be an issue.
