Skill based matchmaking was one of the issues brought up several times in here. I personally would like everything I can do something about to be at least discussed by the team. So this also got attention of team and we agreed that matchmaking needed improvement.
However I am guessing you don't care about that and only interested in design related changes. Well there is simply nothing I can do. And I don't know the answers to your (possible) questions.
And I am aware that you were asking TW in general, not me personally, but if company had something to say, it has a community team for it. Answering from my perspective is better than not answering at all I suppose.
