For the past year or so I have played AoS, the chat section of the game was typically pretty clear, I saw the occasional argument or conversion between but this was it. I don't know what is up with this constant complaining about "COD kiddies" and other nonsense that really doesn't deserve that much attention, but I am sure something besides whining about it on the forums will help the situation.
If it's the fact that players from foreign games (coughCODcough) are coming to AoS, this is a little stereotypical. I played COD : FH, COD 2, COD 3, MW2, MW3, Black Cocks, etc. and I'm not some 7 year kid with 1st grade level grammar and a unstable and immature attitude. If it's a skill thing, ridiculing others for "lacking skill" or being "noobish" is hypocritical. All the games I am good at now, I used to suck at, and I'm sure that applies to everyone else. We had to learn, make mistakes and get better, putting less advanced players under the bus is not the answer to the "lack of skill in players". Just let them play, and let them learn the same you did, or try to help them out.
I don't know what else is the matter with this streak of complaining, but it has to stop. This isn't something I'd expect out of AoS of all places.
