Let me add one more major issue to that list:
There's a lot of people that DO NOT listen. And the community guidelines are about me being nice to them. But quite frankly I think they are assholes and treat them as such. Now for a muse developer: I reported quite a few people for not listening, what happened with those?
Also, this is a bleeding problem. While when I send out a corrective message in higher level games, people will shut up and let my target have it. But when I'm in a lower level game, they even go as far as to ready up so I cannot push the guy to leave or worse yet: they back him up.
I am often the captain and I get regular complaints from people that I'm always yelling at them, I send those complaints right back and tell them it's because they are not listening. But in the end it still stinks. Especially because when I do have a crew willing to do its job, I can be more patient and a much more friendly captain.
