Player rating for tournaments across all installments of Heroes.

Oh! Golden words! Tell that to Gus Hiddink, and he will agree with you! :) Only those who don't see another way to prove their strength rely on chance. The harder it is to break through to the top, the more excitement and interest there is... You play on Impossible difficulty for exactly that reason.
It's good that we have opposite views. Otherwise, we would have abandoned the idea of a rating system long ago, I think... :)
