In fact, the TTK in Ghosts is similar to that in MW2. Or Id even say that MW2 has faster TTK on a really good host or when you host a game on your xbox.

The main reason I quit GHosts on 360 was because of the abysmal connection, huge maps that were designed in a retarded way etc.
MY K/D in ghosts was far higher than BO2. I like the huge maps, not for their camping spots but because I dominated at greater than 40 yards from my target. I always tried to put myself in a position with a marksmen rifle (Man I love the marksmen rifle class of guns) at a far enough distance that the guys with controllers struggled to aim at. 2 to 3 taps with a fast marksmen rifle and they went down so easily.
I felt like Blops2 guns were lacking good assault rifles and was forced to use a light sniper weapon to get the effect that was achieved so easily in ghosts. I really like the short scopes and I absolutely hate ACOG in the COD games. Because pistol shots are a mouse click and not a Right Trigger pull, any hand gun is virtually machine pistol and great for close range.
Just my personal opinion. With TTK so high in all COD and BF games (go back and try CS:GO) to make up for the fact that Console players are lucky to hit their targets 2-5 times in a full clip, I would think more XIMMERS would be taking advantage of the increased precision at the farthest ranges possible.
