apperently more strafting required in this game? it's first shot and your basicaly dead. try to turn around like halo 3 and out br,dmr someone who has the first 2 shots in it. I bet you can only do it 1/10 out of the time now instead of 6/10 the time. People have to be god awful for them to fail after hitting the first 1-2 shots because the game doesn't have that big of a skill gap anymore.
and as a secondary Boltshot is OP i use it just because others use it lol.
