Maybe its time to get me in here.
1.Moreover my message ended with a "Kappa" what suggests that the message is kind of ironic or should not taken seriously.
(...)
2. You went "afk" on a point where we actually were winning this game. Despite many message in TEAMchat (didnt get saved in replay) where I wrote if you continue fighting and winning us this game, its totally fine and i dont care or even report you. But staying in base and loosing an 1h+ game on purpose is what got you the ban. It can be compared to team killing, etc.
So that sturmpanther also was in this game isnt the reason that got u banned and no one "abused" their moderation power.
The problem here is that you and Sturmpanther can't be unbiased in this setup, so it should not be handled that way.
Yes, he did not play very well, and new/bad/casual players do not have high micro and therefore camp a lot more. That's not a bannable offense. Still you (lightly) flamed him for that, and the "kappa" does not change anything as you clearly meant what you wrote (also it's a very niche word and you can't expect everyone to understand it, even if what you wrote were meant ironically). He then got triggered and showed poor behaviour in return to end the game a bit quicker.
I will have to watch the replay again, but from what I remember the game was pretty much lost. There might be rare occasions where you turn around a game that with the last VPs and bleed your opponent to defeat over the next 15-20 min, but these are the absolute exception. With those 20 points even a small mistake could have ended the game for you. And even assuming that Heat did not contribute anything you were playing 3v3 for basically the whole match and bled to 20 points. Again, I'd need to rewatch the game, but I don't remember you killing the central Axis units at the end of the game (although I was obviously focused on something else).
Short summary from my perspective:
You flamed a casual player for playing casual in random matchmaking. That player then reacted poorly, which in the end however did not change the outcome of the game.
Obviously, feel free to disagree.
