Yes, and no. Yes, it plays the same at the basic level, as in if you kill a player, the game drops a dog tag confirming your kill, and you can obtain it (if you're close by). If someone else kills the player in front of you, it drops a red tag, which you can obtain as well. It works the same way as they do in MW3, Black Ops 2, and Ghosts. No, because the difference lies in the gameplay itself - you have all of these new movements, right? You can now pick up your dog tags in/on places that weren't possible before. So, killing others will be fundamentally required now - it's now a game of "the fastest team wins."
I guess you're right. Seems silly you might see a lot of dog tags on top of buildings and in mid-air, but it will be refreshing.
