The thing is while there is a distinction between a incapable player and a troll, some incapable players are asshats. Don't know how to fire a hades or a lumberjack, fair enough. Not good at keeping up chem cycles because you haven't learnt them yet. Okay. Have an silly loadout when you join and want an explanation for why you should bring something different. No worries.
You haven't played the tutorial, not okay. If I try to compromise with you and find a loadout that lets you play the class you want,and you insist on bring buff/chem/ext with lochnagar, not okay. You go pilot without enough experience to handle the role and responsibility and don't run it past your crew first, not okay. Under pressure you insist on ignoring your crewmates and captain. Not okay.
Sure you aren't trolling, but you are an ass. I don't want you banned, but I also never want to play with you again.
As to the ideas presented. The idea of using positive reinforcement is fine by me, it is what the commendation system is supposed to do. The calls I see for reforming the commendation system miss the point, it is a psychological trick to get people to behave, it works on the edge cases, and comprehensive rating system for people is unlikely to make matters better.
As for the tribunal system from LoL, meh. By reputation LoL doesn't exactly have the best community on the internets. But, I don't care, give the CA mods and CA a bit more power, a bit less, tweaking it to find a happy medium is fine by me.
I don't want to rank players by some rating system, what would it do? I still either join on my friends, who are mostly decent folks from what I can tell, or I join via matchmaker in which case rankings wont do squat without some complex datamining (affinity analysis? Are we thinking of getting the folks from OkCupid in here or something to do this?). I don't especially care to the details of how we police trolling, be it the current CA system, or some variant of the tribunal proposed. What I want is greater control over who I play with.
I want this because I don't see trolling as the major problem, I report and block trolls pretty quickly. The problem is asshats, and you cant ban people just for being asshats. At the moment we have no way to avoid them.
