The short story is; you're on the right path, but you still have more to do.
The Tribunal isn't unfairly picking on you. I spent some time looking into your case, taking a holistic approach to your account, it's past tribunal history, the reports it's accrued, and even reviewed the chat logs of specific games.
You've made a lot of progress from your first Tribunal Case. You're not really overtly toxic anymore. You know the kind of person with insane rage, and foul language.
But you're extremely passive aggressive. When you want to rage you still express it, you are just more subtle about it.
This has paid off for you.
You're not getting suspended very frequently. In fact, it took over two months from your last suspension in the Tribunal to judge your case guilty again.
But eventually that passive aggressive behavior is going to catch up to you; as it did here.
In Case #6094665 what most likely did you in, was when you announced to your team that you were not going to play anymore thanks to the Kassadin player.
Giving up on a game is simply unacceptable and the Tribunal Community has a very low tolerance for someone who will complain throughout a game and then decide to stop contributing.
But don't for a second think that you were banned simply because of these three matches.
It takes a lot more than just three matches to get a tribunal case.
In your situation you've been reported in over 70 games since your last Tribunal Case two months ago. The Tribunal merely randomly selected three matches to be displayed.
A lot of these reports are for similar reasons:
- Consistent complaining throughout the match
- Unproductive criticism of other players in your games
- Complaining in all Chat about specific champions being for "noobs" or "face-roll" champs to insult others. (Why is it always the Kassadins?)
- Complaining in all Chat about specific strategies, like jungle ganks and insulting others by claiming they can't win a fair match and need to be "babysat"
- Deciding to just give up when a match doesn't go your way. Even if your team ends up winning in the end, there is no shortage of criticism from you about other players; their strategies, or their refusal to listen to you.
If you're genuinely interested in avoiding future bans you're going to have to move on to the next step. Not just avoiding outright foul and abusive language, but ensuring that you're a player people actually want to play with. Don't be "that guy". Avoid the passive aggressive criticism, the constant complaints, and the refusal to finish matches.
If you need one particular tip it would be: just don't type anymore. Your team mates and opponents don't appreciate it, and it's getting you in trouble.
Just stick to calling MIA's, jungle timers, and good pings for map awareness to communicate with your team. That's the core kind of communication one needs to succeed in this game anyways.
Best of luck to you.
