DEVS, please read this and consider, because booster smurf abuse and ELO infinite widening will potentially make the hidden names and rank change very BAD for team ranked.
The hidden names and rank change should only have been added together with anti-smurf changes like limit family sharing to play single user only and change of premade mmr calculations to make boosters useless etc.
You should also have added a cap to ELO span widening for long queuing and possibly even a max ELO diff match making setting to let the players themselves decide on how long they should wait for even matches.
Finally, you should also sort players in team matches better. I have studied games on aoe4 world and found that even multiple solo queuers in a 4v4 eg are not sorted to make teams even, they probably just throw them in a random team as is now. I even have a theory that the longer you wait the higher the chance of ending in same team due to in queue first, hence being the cause of highly uneven teams.
Do all of the above and I love the change with hidden matchup. But sadly, since you didn’t, I fear this change will make life worse for most of the team players, all the casual ones who just wanna have fun and don’t care equally much for climbing the ladder. I fear they will quit in game now, or even quit playing the game completely after some time..
