Well, here is the thing, I have no faction preference (having always switched back and forth). I heard the ratio between Alliance and Horde is rather "even" (with Horde having only a few more). Now, with that in mind:
1. In which faction will I have an easier time with progression? Finding dungeons, heroics and raids...
2. What about PvP? Is there a dominant faction? I simply do not want to loose every time I queue for BGs.
3. Overall quality and maturity of players. If one faction is dominating, it is most likely due to people simply "sucking" at their class. In other words, I want to know which side is prone to do what they are supposed to do, like doing the objective while PvPing and not standing right next to a boss's AoE or pulling things before the tank holding aggro.
4. At last but not least, what about friendliness and the least amount of jerks and trolls (no, not the race)?
