Should Social playlists have a cap on parties?

Even before Achilles was introduced, “Social” playlists have seemed to have a problem with balance. And I know, they’re not really supposed to be balanced, but I’d argue there’s a difference between open and exploitable. These playlists are supposed to be for casual play, but I ( personally) have run into several (especially after assault went live) instances of playing a “social” match against a team of coordinated players that refuse to win the match before farming as many kills as possible from my team of rando’s. Just saying, maybe drop the party size to 2 or 3? (And add a 5 v 5 Ranked playlist of course).
