Regarding autofill
It's not that I have a problem with getting autofilled support per se (mage support main), it's the reactions from teammates who are forced to support because THEY got autofilled that seems to be a common issue.
Sure, back before the mid season 6 changes, pick order often screwed people over, but I actually thought the new system of choosing roles was an improvement. The people who supported, genuinely wanted to support. The game wasn't so dependent on which botlane support cared/was more skilled.
If that means a longer queue time to get into a game, so be it. I would rather have higher quality games at the expense of a little more waiting time.
