Riot needs to release a video to show how "great" support is
Buffing support items hasn't worked. Shoving weaker mages into the role hasn't worked. Autofill hasn't worked. People still don't want to queue for it. Autofill is especially bad, because then we get player who are both angry they didn't get their intended role and inexperienced with support.
What we need is to show the community that, despite the fact this is an entirely combat-based game where the word BATTLE is literally in the genre's title, the role where you don't get to do the battling for yourself is fun.
You know, barring any changes that would actually make the role fun for more than 5% of players.
