Look, I can see where you're coming from about the over-emphasis on winning; but it just sound like you're talking about an entirely different issue to what Valve is trying to address.

Your suggestion, if I understand it correctly, is to have the game automatically make a judgement about every player's individual skill during the match itself, and apply some buff or penalty if it detects a major discrepancy between players. Is that what you are suggesting?

I suspect that the existence of mechanics like that would lead to a lot of angst, regardless of whether it 'works'. People already have a tendency to blame their team and blame match-making for making them lose. Imagine if they could also blame the game itself for holding them back. ... It could be a perfect system that never gets it wrong, and it would still cause a lot of people to get upset. And I don't see how it could fix the problem of smurfing anyway unless it is a seriously over-zealous system that erases basically any skill advantage.

Also, I don't think such auto-detection would be reliable. But although we could could discuss the technicalities of what might or might not work... I just don't think it's worth pursuing in dota anyway. Perhaps it would be better suited to some other game.
