What if everyone had to support?

I mean what if everyone automatically had Support as a role set, in addition to their normal roles they can choose? (perhaps just for lower-mid elos, as high dia+ is kinda a world in its own, one tricks, pro players etc)

Obviously a lot of people "dont want to sup" and I'm not here to really argue their motivations for not wanting, or wanting, to support (although playing from the support perspective provides pretty valuable insight into other aspects of the game that every player should learn).

But if the game just queues us up with support as an option every time, for everyone, then in my crazy mind the amount of times people have to support each would even out and people wouldn't get sup every game unless they're really unlucky

I mean take my recent match history for example - I've queued as top/support to primarily learn support, knowing I'll never get top (the one diana game i was fill/sup), but if everyone had support auto ticked, there would probably be a bunch of Irelia games in the mix there.

While I don't care (I'm using this alt acct to get good at thresh) I see a lot of people talking about a limit on getting secondary roles as well as another option. Obviously it likely wouldn't go anywhere due to a lot of people refusing to play support outright but just throwing some concepts around (and support has arguably the lowest skill floor as far as roles go)
