Autofill really pissed me off

About autofill. I knew riot is trying to let us play more lanes and try more champs to make this game have more fun. But the thing is, if it's in ranked and u go autofilled, an unfamiliar lane u never played before and it's ranked. No one wants to switch with you(mostly is support) and I gotta keep playing. Feeding because of bad, that's really not fun in my opinion. Teammates being toxic to me because I'm bad at that lane, bc I don't even play that lane! I should get into my best lane, play my best champion in ranked but not like that. In some important games I got autofilled to support which is my worst lane and my adc is always stupid. And I can't do anything but lose. I really don't mind to wait longer to get in the game. Got in a game and failed is really not how it works. In normals I don't care but ranked, that really pissed me off. As a silver/gold player, I really don't play that many champions and that many lanes, and my team is not always good. I wish riot can do something about it although it's hard to come true. I'm just really sad now after I just lost the promo. I love this game I played for 2 years, never played other game since I met league of legends. Well even they don't do anything about it, imma still in it, it's like weed, I can't cut it off.
