They actually insist you just make a new account if you're permabanned. So they basically insist toxic players reroll and make smurfs. But lets keep pretending the punishment system isn't broke, and isn't having vibrating consequences on players like this one. Trying to play with friends new to this game.
You can pretend they'll fix the game based off mmr all you want, but then they just int troll and feed, also a system abused relentlessly, because it's only worthwhile rebuking the vocal players. This game is just trying to kill itself off now so they can start a new one.
Edit: this is why you're able to have multiple accounts linked to one email. They genuinely adore it when you make another one. Smurf, alt, reroll account, w/e you want to call it. They love that you've made a new account to potentially buy something, or to inflate the numbers of players "coming in" to the game.
