I'd like to know if I've broken the game etiquette, because if it's the case I need to apologize:

I'm in a game, the classic Uberplane against mediocre enemies (btw I like a lot this kind of games, because you need to cooperate with your inferior buddies in order to catch the superior enemy), with the also classic 12x10 large map. After a few turns I've pointed to my (german) collegues that we should stay on the right side of the map because otherwise we would have seen our planes shot down when we finish the fuel. My allies have 200/300 games, and our opponent many thousand.

I've been mildly reproached, and I really don't know if this is a violation of the game etiquette. Thank you for any feedback.
