Autofill - And why it causes such anger (no its not because I dont want to play an offrole)

I want to start off by stating that, I dont care if I get autofilled (because I never do.. I know how to never let it happen).

So when you search the forums for autofill, you see 100,000 post all talking about how people don't want to play support and that they can't carry their team blah blah blah.. I don't think that's the case at all. I don't think that's what the issue is... Now I know that riot mentions that they try to keep it fair on both sides, (i.e. if 1 person is autofilled on your team, should be similar on the othjer team.). But those roles are rarely the same role.. So if my team gets an autofill jungler but theirs gets an autofill support, I think it'd be fair to say that those 2 roles have different levels of impact on the game..

My main argument though, is that, the game is no longer about who makes the best plays or decisions that wins the game (solo/duo queue).. I believe it's more about which team makes the least amount of mistakes.. And with as much damage as there is in the game today, having someone on a champion they are not comfortable on, can be really costly.

Just a different perspective.. I want to know your thoughts!
