Disclaimer: I haven't really played a COD game since Black Ops (I beat the MW3 campaign while drunk), but I used to play it a ton. Like 20 days of COD4 and probably another 15 days between World at War, MW2, and Black Ops.
That being said, over on Jeff's Twitter, he was saying that people were spamming replies at him because Sledgehammer mentioned him in a Tweet. One of the things a lot of people seemed to be complaining about was ranked matchmaking (or whatever term they use for it). This strikes me as odd, because that seems like a good thing to have in a game. I'm pretty heavily invested in CS:GO and if the competitive mode in that didn't have some kind of ranking system, it would be a total shitshow. I was just curious why it was such a big issue (apparently) in the COD:AW community.
