You can discuss all you like, but the simple fact is: Those, who only want to play opponents of a certain rank, already do so. There are plenty of players hosting their own private games with minimum point requirements. To introduce this as an option when starting a game would only make it easier to start, find & join these games. With other words: Customer friendly ...

And by the way: Here a low ranked player complains about a high ranked team joining his/her team game "for easy points" and spoiling the fun of the game for his/her team of casual / not competitive players. It“s not the first time, that I heard a complaint like that. So I imagine, that the option to exclude players above a certain rank from your games, especially team games, would appeal to quite a few low ranked players as well.
