Why would players on a server vote or not vote to kick someone of an opponent's ship?
I said it because it requires convincing other players that there is a jerk on a server that destroys the fun of the game. I think it's also important for opponent's team to have challenging battles .
But ok, maybe You are right it's to much for a whole server to vote but leaving a voting option just to one crew could lead to abuse IMHO. As Smollett said, this could result in kicking players just because a captain (or the rest of the crew) don't like something about one player in their crew (to small level, no microphone, to make room for somebody else etc.).
That's why I think a neutral voice is needed here, like the rest of the team (or whole server). Somebody you have to convince that one player in Your crew is a pest so that he can't be kicked only because of one's captain selfish reasons.
I still stick with the idea of thumbs-downing someone being an option. Muse could see if someone is being an ass and trying to 'report' everyone they come across, or if they are consistently a negative player at a glance. With the larger number of inputs, it removes the he said, she said that Gilder mentions.
But again this could result in giving negative commendations to players who are still noobs. Innocent people would get negative commendations because they are not yet experienced in GoI, had just bad day as a gunner, haven't manage to do some orders taken from pilot or just someone doesn't like someone's voice.
It's the same reason why on Facebook you don't have an "don't like" button. You either have many commendations what means you are a good player or few commendation what means you are either a bad player or you just started playing the game (or because commendations is a new feature and you are an experienced player but haven't managed to gain them yet ^^').
I've had a few teammates who just refuse to listen but they are the minority. In adventure mode a more "these guys only" approach makes sense but in skirmish where it's brawl for fun I don't see a need for elitism.
It's an awesome thing that this game has such a great and willing to help community but think about the future. I mean, I hope that GoIO will one day become a popular well known game than just aprovincial, cosy game for a small group of enthusiasts (no offense). If so then we should be ready for an influx of pricks without good manners raised on Counter Strikes, CoDs and BFs (also no offense xD). In this case there should be a way to deal with them.
