Problem With Role Selection

Yes, I am complaining about autofill..... but not about me being autofilled; I am here to complain about everyone else in my game being autofilled.

I currently main jungle and support, as a result one would expect me to be playing support almost every single game; However, In the week or so i have been queuing this way, I have not been put in the support role once.

What is more worrying is that in occasion I see someone autofilled support and I usually switch with them.

Thoughts?
