I don´t know what do you expect, at least ingame. Theres no point of comparison between EvE and COH2 or any other game which is not an MMO. By sheer number of players and gamedesign, you are forced to cooperate in order to suceed. If we depart from RPG, we can look at what Planetside 2 has done to promote or force playing at least as a "coordinated" zerg.
Besides some gentlement words such as Hi, gl hf and wp/gg and the end, what do you expect? I dont play random teamgames due to spamfest and little coordination n tools to do so, but is expectable that many people are just gonna blame others rather than themselves. It happens everywhere.
You also can't fault 1v1 players for not giving the other player tips because let's face it, most people just aren't that nice. Just seeing a "gl hf" is already asking for a lot.

Negative comments only affects you if you let them do so (This is more a personality thing). If you are received with negative comments, just smile, wave and ignore it or put your nice guy mask and keep answering them with kind words. They either rage quit or end laughing due to the unexpected answer.
Also, ask yourselves, how many times have you seen German/Russian OP threads in comparison to How can i improve my game or How do i beat X strategy/opening? Most people aren´t willing to learn. They just want to derp around, thing is, i don´t see this game as an optimal one to do so.
