Hope it has a slightly improvement in existing matching system (not for 2v2 arranged)

[Juslas]

There are only 100-120 doubles matches completed daily. Can assume same number is started daily.
Therefore Alex's decision combining arranged and random has a point. But matchmaking feels off as a player perspective, because of Alex's choice.
I feel random partners play really poorly, regardless they league or ranking. I strongly feel that excluding arranged teams would make things much better. And random would fight random with random skills.
Also matchmaking needs to have steps that widen the search for partner and opponent. It sure feels that there is just on and off modes now.

When next season starts: please separate random and arranged from matchmaking. We can go back to old system on season after that, if experiment fails.
