Being autofilled every third game feels awful

Mostly just posting this as something for riot to hopefully see, as I think they do a pretty good job listening to our feed back. I have played 7 games today, gotten autofilled 3 of them, and like, man it's not fun. Don't get me wrong, I'm ok with filling in every once and while, I'm happy to support, but with that many auto fills, and the fact that you don't always get the main role you q for, its prohibitive to having serious learning goals. I was super excited to try and practice trading when the enemy adc goes to last hit casters today, and by the time I actually got onto my main I had been filled into so many other things I was just disheartened, and unfocused having been unable to warm up and settle into the groove of playing ad. Long q times suck, but it sucks more to be forced off the things you find fun and interesting over HALF of the time. What sucks even more is that much of the time I was auto filled AFTER getting into champ select on my main role, and having someone else dodge. The real kicker here is it still took over 10 minutes to get into some of those games. The waiting itself I can handle, being in q/champ select for 15 minutes only to be autofilled for the third time of the day was a really REALLY bad feeling. I know autofill needs to exist, but maybe it would be worth giving a longer cooldown to autofill, or 3 or 4 games, or having it increase the cooldown if you got autofilled then autofilled again right after two games, so that now that iv been auto filled 2/4 of my last games it will protect for say 3 or 4 more games. Alternatively it could "lock" you into the role you received before someone else dodged so you don't have to wait 15 minutes to get autofilled. Just some food for thought.
