Any Ideas for improvements for supports second pick in the flex and ranked queue system?

Hi everyone,

I am doing this for my first time, but wanted gather some opinions. I am a midlane main and i would like to play support for my second role. I would not mind to play 50% of my games as support, but you all know what happens if you select first: mid and second: support. I guess that this issues takes many players away from going for support second at all, so this is my idea: After you got the support role in one game or multiple games in a row, you are allowed to select only one position for only the next game. I would not mind if there was still the possibility for autofill, since its improving queuetimes by a lot and happens seldom in lower elo. I would expect some growrates in support player base since you could kind of guarantee your main role by supporting your team for one time. Since this feature is specific for one role, there could be no issues since if the support queue was overflowing you just get your primary and support mains still get priority since the select it first pick.

Hope you guys want to discuss some ideas for changing frequence of support second pick to about 50% or less.

Have a nice day
