This is posted at the upcoming AoE update. To makes thinks clear: This about AoE, not AoE II.
I am not really into AoE, but it seems like AoE had also some issues. The devs even decided to reset the ladder.
I hope they will fix the AoE II Team game ladder also at some moment. I dont know if the devs will also reset the current rankings on AoE II after they fix everything.
I also found the following picture about the team game ratings.
