I guess the only other thing I can think of at the moment is maybe when you hit Platinum the game just locks you off from partying up with x2 people in ranked. Most people sort-of know each other around that sort of veterancy bracket by seeing familiar names too. So while people can queue up x2 to try help each other in Bronze -> Gold and for the most part that's accepted, there comes a point where the game says "okay you should more or less be experienced enough now to go it alone for the real deal" as most veterans sort of think about queuing ranked by themselves for more serious competition. Would also give players a sort of goal to get to as well I suppose, hit Platinum and it's like a badge of honour with benefits of more tighter matchmaking algorithms? It'd also keep Masters players happy by sort of staying in that sort of bracket rather than smurfing (and if they did smurf to boost other friends accounts up by duo queue, the matchmaker would quickly suss it out...
Masters players overwhelmingly wanted duo queue to return.
There is no easy solution to these challenges. There are huge teams of people spending years reviewing data and making tweaks to matchmaking systems and yet every game players complain. Dont put pressure on yourself to find anything perfect right here and now.
