This autofill bullshit is getting on my last nerve, RIOT.
Now, I don't mind supporting once and a while, but when I get stupid as fuck support picks on my team, then it starts to grind my fucking gears. This system, within the span of what? 3-4 months? has ruined the experience of my games DRAMATICALLY. I've literally uninstalled League 3 times now because my ranked games are literally corrupt with meta-mancing support picks, like support shaco who builds an ancient coin, then rushes gun-blade. No sightstone or control wards needed. This is one example out of, at least, 200.
Yes, I understand that the system used to be similar, in the sense that if you got last pick in the old client, you "most likely" got support. But something needs to change, it's literally ruining ranked guys.
