Supporting/filling should guarantee our primary for the next game instead of autofill protection.

Having support/fill as your secondary has always caused you to rarely get your primary, even after Riot supposedly fixed it. Because of this, people who enjoy supporting, but don't want to support in 80% of their games don't put support as their secondary and instead put a secondary they enjoy less just so they can get their primary more often.

If Riot isn't going to fix their algorithms to make support/fill secondary not suck, they could solve this issue by having the next game guaranteeing your primary after supporting/filling. This way you are supporting/filling at most 50% of the time so it's more fair if you want to play other roles.
