In the previous games it typically has been around 1.5, with 1.65 being my highest near the end of MW2 before BO. I also play aggressively for Dom and HQ points and CTF, so I die more frequently which I am okay with unless its TDM.
This game has been tough. Sometimes the lag and lag comp just effs me over, spawns haven't been too bad except for a few times. The SMG laser hip fire cheese isn't working for me. So many times I should have killed guys but it's like they don't get hit. Or getting sniped after I back around a corner.
The only guns that have been good to me are the M8, T25, 870 and Ballista. Oh and any pistol. The OP SMG's don't work for me go figure.
I think I'm at 2.02 right now, but I've been hovering around 2-2.1 recently. The maps are so tiny and spawns are so scattered that it makes enemies appear all around you, making it super hard to go on long kill streaks. I was at a 3.5 in black ops and 4+ in mw3
