How many factions are there?

Nah... It seems now that the more factions there are, the better and more interesting it is, and so on. But in reality, you'll play for a month, and it will all get boring. New factions will stop being new, and the interest will fade. In my opinion, right now, the balance is perfect: four factions that are conventionally evil, and four that are conventionally good. And if you were to add any, it should be at most two – one good and one evil.
