I do like where Jay was going when he was on his own little tangent about implementing it into Diablo 3 though. A difficulty scale that would surpass the 4 person difficulty would add more challenge to the game even after you're 60. Just imagine getting the best gear in the game at max level and still struggling to survive as you progress through the game. Maybe that's just me though...
I like that
