Autofill sucks
Exept it doesn't, autofill is the equivilance of ballance and also proves your true skill. Hello any OTP you just got autofilled to lane you almost never play where did all your "skill" go? Hello only 1 or 2 lanes player that got autofilled somwehere else how come you can't play the same game in a diffrent area? The truth is that you don't try because you expect to perform less than on your main lane or you're just trash and can't play other roles and some of them are actualy way easier than your lane you prioritise...
If you think that autofill is ruining your climb or you just overall hate it here's something: My name is #IDON'TGIVEADAMN and I play Solo/Duo with primary lane Fill and secondary lane Fill, I get all kinds of roles besides support and I don't care which I lane I will play at my optimum level always better than most of people in game and on most lanes dominate them. I don't care if I was playing last game some strong character and next I'm playing fragile support or squishy assasin I am not trash and I know my strengths and weaknesses. How come you can't be like me? So far have positive winrate. Don't need to warmup just jump in straight in ranked my performance always good. Progress of climb is felt.
What's so hard playing other lanes? If you so good at the champ you can play it almost every lane or similar. If you say that you're good but hate autofill because you lose most of the time you get one it's not autofill problem but yours.
Playing a specific lane alot with sometimes going supp or fill to activate autofill protection makes you almost immune to autofill even if it's activated.
I found myself playing more than 20 games on lanes with autofill acivated and those lanes are popular.
Honestly if you can't play autofill you don't deserve to climb imo.
