Dont get me wrong it should be great fun, but honestly who here is'nt planning to become a Luxon? Its gonna be WoW all over again with no Horde/Kurzicks and a million bored Luxons/Alliance.
I mean who wants to be a stick-in-the-ass gothic zealot when they could be throwing back cold ones with their pirate buddies in a Luxon camp?
Please reaasure us that there will be something more appealing to the kurzicks than chastity belts and black robes

Except that ANet's already said you'll have to choose a side. On the preorder box it says, "To all who would proceed, take heed... All must choose a side." They've even gone so far as to say that it's doing quests that will determine which side you're on, as the quests will be for one side or the other. You'd then be able to switch sides by doing quests for the other side, though it would be slow going at first because they hate you.
