glad someone mentioned already that there are literally no Teenagers playing this game
I feel sorry for Wargrimmir in this thread ... the amount of "gamesplaining" in his direction is hilarious to read !
But on a more serious note: solo queue will always be bad ! because we have a big number of people who always play "alone" (not solo, different Players) because humans learn from each other ... and people who dont interact with other people in this game simply learn less (and yes there is also a subcategory that talks a lot in public chats - but has only output. Input is just blocked

).
The difference between Queueing and meeting "Group Players" (who only queued solo because of - random reason) ... vs our "Pool" of "alone Players" is huge.
That problem is not "fixable" with any technical solution.
