Autofill
While personally I think autofill is a stupid mechanic that should be toggleable, this isn't one of these posts. Recently it has happened to me a lot where my first preferred role was support and second would be jungle or mid or something. With the current autofill system even if you queue for a role like support, which usually gives you autofill protection, if you get mid when it is your secondary role you still get autofilled. Am I the only one that thinks this makes no sense?
