Your response doesn't address the problem... literally at all.
We just don't want to be forced to play with strangers to be able to receive the same awards as everyone else. This isn't a difficult concept to understand. You play with randos-- good for you. Some of us would rather be given the option whether or not to do that, not be left completely unable to complete the challenges because of it.
As an autistic person, I struggle with social interactions with people I don't know, especially over voice or video media. This is not a voluntary response to those situations.
Being forced to group with someone, I'm left with two options: A.) Suffer through undue discomfort and stress to interact with a person I'd rather not interact with in order to complete some arbitrary challenges in a video game; or B.) Forego the rewards of those challenges and simply not play.
I can tell you now, if I'm made to choose enough times, it will eventually always be choice B, and that choice will become permanent. I simply won't be back, won't be playing their game. There are probably thousands of other players that feel the same way, and for game developers, it's not a good look to have large groups of players leave your game because you made them feel alienated and then didn't do anything about it.
