Even if unranked games aren't supposed to be sweaty and "don't matter" it's still wasting people time if players are ignorant/a bit clueless and just pick w/e and making the game harder way more than it should be…
Talking about cases where:
– Comps are support heavy/not having ideal heroes for roles
– Forcing players to play role they are not comfortable just for the sake of trying to save "failed team comp"
– Players picking Bane and Clockwerk for example as last 2 picks when our team needs Pos 1 and Pos 2 hero just because they wanted to play supports but someone picked supports over them and they still don't care 😀
There might be other cases but personally i lose motivation if i go into the game knowing i'm not playing what i was supposed to just because someone refused to communicate in pick phase!
