New ideas for ranked teambuilder to decrease queue times and toxicity

1 idea is to bring back team capatins, and they decide the team comps while players join teams.

They can make the supply and demand work so that everyone has a similar Q time since captains can choose what roles they want on their teams.

For example, a team captain who thinks that the typical 1 top 1 mid 1 bot 1 supp 1 jg team takes too long to find, they can set up a team with 1 top 2 mid and 1 jg and 1 bot if they want. This will mean that more mid lane mains will get the role they want without being autofilled into another role just to make queue times reasonable.

Another idea could be a computer system that automatically does this without team captains. If the computer system senses too many people queuing for mid and not enough for support, then they will automatically assign teams with 2 mid laners and no support. I'd rather play in a duo mid than to be autofilled to a role I don't play at all like jungle. Players could also select if they want rigid teams with longer queue time (1 mid 1 top 1 jg 1 bot 1 supp) or fluid team comps based on supply and demand and have shorter queue times.
