My biggest thing with COD is its community is always talking about how COD is the best and how it has the most skilled players and people that say otherwise must just be bad at COD. Not really responding to a particular person in this thread, but the COD community is very elitist and it makes it a joke.
Even the skill gap between COD and BF3 is enormous. I get people pick the game they like and that's cool. But the COD community does this to themselves when they look down on everything else even though they play the easiest fps on the market.
