but to answer, tribunal does what it does and does it well.
I too would like to see more evidence when I review tribunal cases, but until then, there is only one simple solution to your example:
Learn to control your emotions and learn how to deal with losing. I'm not saying this to you but to all the ragers out there.
In your example, you're saying that the rage is induced by the other team. Well firstly, this is a game, cheese strategies are still strategies and it's not CHEAP. Secondly, we are in control of our own emotions, if you can't control them and focus on winning and teamwork, then it's your fault, not the other teams. Lastly, tribunal only reviews text and score. If you don't say anything even if you're mad, when people review the case they have nothing to go buy. Most people will skip or pardon in those cases.
You're right about the defendant not being able to defend themselve, but the other side of the coin is that you can defend yourself in game to avoid heading to the tribunal. Someone argues with a troll, or troll/rage with other people, well then maybe they deserve to be in tribunal.
it's not hard to avoid heading to the tribunal. it's just that most gamers don't have the skill sets and knowledge in how to handle thier emotions. These are things you learn from real life experience and organized sports.
