yeah, i've been playing arma2 online for one month. The coop mission online are chaotic and you can't simply have anyone working together since half the player known each other from clans and the other half are somewhat, had and objective goals but clueless in teamwork.
Dominace are for player who surely have nothing to do but "Have some fun, with lots a great people" sure teamwork would works but when those fly boy took the jets out and add extra hour flight with enough payload to flatter a cities, well that's sum it all up. No more pressing the "W" for 10 minute just to get to a clear spot and took out a binocular only to see the objective is cleared by those fly boys, and they actually have a laugh about it in your face! Cannon fodder player are not to blame for the decrease experiencing of the games, rather they serve a purpose to fulfill the role that you had previously "evolutioned" from. They rejected to conform since some player are having 17 death and 250 kills from jets. Look from the perspective of ground soldier in modern warfare. They would be hailing and cheering the jizz out of A-10 sweeping their wings and droppin their bomb. But in game though, you gotta give some coutersy, cuz other player also have a rough days outside and finally home to get in on the action.
I just think that you are being rejected by the other player because you play in your own tactic that doesn't appeal to the majority. Try saying hi and salute people,show them you have respect for them. and try not to run in front of other player cuz it will just meant that you ignored his line of fire therefore, "you a bad tactician!" and also remember "CO-OP" meant work together not make name and glory.
i rather join server running unique mission like castle or hunt waldo. Player in those server are more co-operating and have a good sense of humour. I'm red by the way. Player you should seek mentor and follow their characteristic of games play are like 50 cal syringe and NZARMA.... Sorry spool lyger, i shot ff your UH-1 with my grenadier during enemy assaulting our base. but you fly boy had enough fun ^_^\. salut
