Oh God, not shields again.
There are going to be some very pissed gamers playing on the TDM/CTF/SAD modes. See how that one guy with the shield never fucking died. Not once, and the flag runner was able to pick off all the guys trying to kill him? Now, maybe it's just because all the people who were playing sucked ass (they did), but it's just going to get worse.
What's going to happen is you're going to have teams of five people in row or a circle so they're surrounded by shields and you're going to have to throw a nade or shoot at their feet to kill them, and people are going to bitch till no end.
Also, I hope they don't release another COD after this one, so the community doesn't fracture so much. COD is nearly dead for PC.
One more thing. That trailer was like a week and a half old.
Last thing, this game is > every cod.
