This is related to what mercman posted earlier about player etiquette, but probably does not warrant the same attention. I've been playing on the server for more than two years, and it still surprises me how some old members still do not show a basic level of respect to other players.
I was on the infected team with these three particular members, the score was close, and we were playing on the hard rain level where the elevator goes up. Being unsuccessful in stopping the other team from going up the elevator, they just ragequit right after, and one of them says before leaving, "I bought 4 spitters.. and you guys still fail..Now I know why [player A] left, I'm done," in the most conceited manner.
Normally, I wouldn't waste my time posting about ragequitting, as people are welcome to join and leave as they please. But these members, especially the two out of the three, have done many disrespectful things in the past as well, and they always (the keyword is always) leave the game when the going gets tough, and subtly stack by d/c and connecting again. Just shameful... and the most amusing thing is that they have not shown any considerable improvement in teamplay even after 1 year+ of playing on the server, and yet they have perfect expectations from their team. (Please.. you are not swatfishy or general or chimi) You'd figure these members would show some maturity even after all this time.
