How to reduce number og afk's, and increase chance of winning with afk

So lately I've had lots of people going afk in ranked games, which have now impacted my rank. I do know about the "remake" command, sadly it doesnt work if they went afk 2 min ingame.

Now, I actualy want some tips and tricks.

How do i reduce the number of RQ's? I know i cant really reduce the number of people who dc unwillingly. And how do I increase my chance of winning with an afk on my team? I mostly play adc, so when the support is leaving, how do i play around that too? I get tower dived a lot when that happens, even with full health.

I know i might sound tilted, maybe I am. But, i'd really like some advise, since this happens too frequently to have an impact on my rank.

Thank you
