I don't agree at all. I think that, as demonstrated by the week or so after Christmas, this game is not noob friendly at all. Sure, once you get the hang of the game and learn the maps, you'll do pretty well, but until then (probably for the first 12 hours of gameplay), you are going to get so fucked up. I still get people on my team who are in first prestige (non-70s) from time to time and from my experience, they always get stomped so hard. I'm talking like 2-25 stomped, not 10-20 stomped.
At this point in the game, you really need to be patient and committed if you want to play MW2, and know that you're going to get, like someone said about, your dick kicked in with an steel-toed boot.
