+1. Usually it's only the losing side that asks for balance. The winning side doesn't seem to be bothered by it in the least. People always gravitated towards their faction's server. Even with BGs and arenas, people did that so they'd have "the best people" to choose from as their teammates.
The only way to create true balance is to completely ditch servers, have one massive server (assuming there would be a tech that would allow it). And even that may end up with people crossing over to one faction only.

Ask the 60 hordies who were chasing the 20 alliance. Those people find it fun. And it's your 1 to their 60. I'll tell what is "fun": winning.
