Yoshi-P recently said that after trying to get the balance right and get the game to a perfect state, he had finally accepted that it's not possible because no matter what he does, a section of the playerbase will be upset about it, so all he can do is keep trying.

Interestingly, the WoW director recently did a presentation where they had concluded the same thing. There are subjects where the playerbase is diametrically opposed to eachother and it's impossible to satisfy all of them.
