My team is indeed reset because of boosts that my partners did.
Anyone that account shared, or logged another account to raise rating for another player, at any point during this season will be reset, without exceptions. They have developed new tools to enable them to easily link accounts based on MAC & IP address for when you login. If anyone in your team did this, your entire team will be disqualified.
This is why you are seeing so many resets. Additionally, this is why you are seeing sub-2000 rated players also being reset.
I will genuinely be suprised if 1 single Rank 1 team, currently on the ladder, keeps their title. There are already instances of BG's where Rank 1 is currently being given to Rank 10+.
So if you boosted a player during the season, your main legit team is reset because of that ?
