Anybody else autofilled less recently?

I'm a top/adc player and in the past 30 games I haven't been autofilled. I've got either top or adc in all those games. It's quite normal for me to be autofilled every 8 games so I'm wondering if Riot has changed the formula recently? I haven't noticed any difference in queue times either, I get into games fast (usually 2-3 minutes). Does honor have anything to do with it? I'm honor lvl 4.
