Please please please get rid of adjustment in team builder!
It's so terrible, it's a prison, you are matched with players who have no idea what they're doing and you aren't matched against players in the same situation, basically when you see adjustment active, you know you're losing the game and it's most likely going to be an immature toxic fest, please, this is the worst cancer Riot has ever created, it's a worse move than some of the things even Jagex themselves have done
I am very proficient in all roles and sometimes i want to expand my champion knowledge but i don't want to have to play with toxic immature unskilled kids every time i do so, and i can't always test out who i want in draft or blind pick, please end this it's been a cruel and unusual punishment for everyone and it works against everything you've said you're trying to do.
