Yes, but at least by playing every team in the division you've at least got a good idea that the rep from the West is at least the best of the West thanks to them all playing each other, and have some confidence that team is better than at least the 6 other teams in that division. Without any divisions at all it could get even worse if the schedules get extremely unbalanced. It's unlikely, but what if one team happens to play the bottom 9 teams in the conference? That's impossible today but isn't impossible without divisions.There's going to be potential for "unfair" results, but how is the current system any better? The #2 team in the East is almost always better than the best from the West, but the West representative gets to go.
