OP, we want a game where we can play and not be harassed by others for every mistake. Yes, we're all adults here(or at least, many of us are). That doesn't mean we want to be subjected to abuse. Alot of the people I see raging about Tribunal judgments on this forum seem to have some expectancy that they should be allowed to rage at their teammates when the matchmaking system "fails" and they're grouped with "bads". People need to get it through their heads that matchmaking is ideally supposed to ensure that you win 50% of the time, which also means you lose 50% of the time. This means that you can't expect all of the good players to be on your team, and all of the bad players on the other team, because that would be absolute failure of the matchmaking system. This in turn means that sometimes, you'll have players on your team that are below the average skill level for the match as a whole, which means they will do poorly.
In my experience, the majority of reports are rage reports towards whoever did the worst on the team and not legitimate reports. Which is why I find the seemingly accepted thought that "because they reached the Tribunal they're probably guilty anyways" to be a complete joke.
