Broken ranked placement

Hello, I would like to complain about ranked placement matches. Me and my friend played together all three placement matches. I was assigned to platinum 4 and my friend to bronze 1 resulting we can no longer play together anymore. I believe that your ranking system is complex mechanism which considers multiple input paramethers, but this huge difference in ranking for both players on same games, same team, seems unreasonable.

It is working correctly. You can not change people’s rank that much based on just 3 games. Think if you are bronze player (unplaced new season) and you ask GM rank1 (unplaced new season) to play with you 3 games. Say you play 2-1. Do you think the bronzie should now be ranked as the GM1 is?

was your friend playing ranked the FIRST time?
or he did play last season too?
