Support Buff
Riot, since the only way to play a game in a reasonable amount of queue time is support, make support the most dominant person in the game. I mean, like mother fucking huge, tons of CC, absurd damage, wicked burst.
I want Braum passive CC, pre-nerf Zed ult damage, range of Caitlyn, movement of Kalista, tankiness of Nautilus and why not, toss in some Lux freelo thunderlord's action.
Also, make it so support can't buy wards but everyone else on the team has to buy sightstone or they are reported and banned for a day.
It's the only way to make people play support and reduce queue times. Do your part.
