I'll just say how TR are consistently highest in Miller world population. Tonight 43% at primetime, 41% at this moment. Conclusion: It's not only faction balance, but also the player distribution and the ensuing domino effect that keeps on going. When a faction starts winning, they will retain more players and also gain more. This will further boost their success and thus the circle continues. The reverse applies to the losing faction. Now, why are NC the most populous on most servers? Perhaps the faction flavor appeals to the most people and/or they were balanced to be stronger than the others at one point in the game? Why aren't they the most numerous on Miller? Perhaps chance gave TR more organization or numbers at an early stage, enough to counter any balance issues? At any rate, current population numbers aren't just indicative of current balance - The past balance also affects things.
