I'm not the best player, but I hold my own. I was at about a 1.20 kdr, then friday i was down to 1.15 and now I'm on 1.08. Sure part of that was because I was experimenting with different builds, but I can't seem to feel any flow with the maps. I think the best way to explain it would be scrambled. There is always someone there to shoot you in the back, and there is always a teammate there to give you an assist point.
Scrambled.
Combined with the fact that every aspect of multiplayer was pedigreed for the SMG rusher. The maps are large but with plenty of trash set in the middle to limit the sight lines. Ghost was changed to benefit the SMG user.
SnD isn't the same. Very little to no stealth. I'm about ready to give it a break until the patch comes out.
