In DF if you find the performance of others acceptable or not is rather irrelevant. You have 3 choices. Vote Dismiss, leave or just ignore it and just role with it. There is nothing wrong with suggesting politely that they would be better off using a particular mechanic they are ignoring but if they choose not to there is nothing you can do to make them change and trying to insist on it can be seen as harassment.

Personally I assume whenever I join a roulette that the competence of those I'm grouped with is going to be unreliable. If I'm not up for dealing with poor players I don't queue for DF.

At the end of the day standards don't mean squat in random groups. This is true for all MMOs.
