Let players choose up to 3 favorite classic modes that gets picked instead of current Hot mode if at least 7/8 players have the same one in Queue or at the start of match
This would ensure that more popular modes get to see more play, which might lead to better engagement with classic
I assume currently quite a few players are totally ignoring the classic que, whenever the more popular hot modes are not active
We already have the UI for this with "automatic voting"
Where you can just add "favorite" box to mark, and notify player this is available.
