The new Guild Halls in Factions...

Does anyone know what the deal is with the new Guild Halls? My understanding is there will be at least 2 new Halls to choose from. How does this impact all the existing Guilds who already have a Hall? Will there be some option to change to one of the new Halls? Can people who do not have Factions still go to them/play there?

I'm not quite sure. Most likely is..again im not sure, but if your Guild Leader purchases Factions, then he can choose one of the new halls (there's bound to be more than 2 though, otherwise people with just Factions will be handicapped badly), and the rest of his guild can go there.

guilds that dont have access to purchase the new halls will still be able to play enemy Guilds that have a new hall, in that new hall.

Um, once the 2 new halls are out. Go buy a sigil and switch. If there's a catch like your faction needs control than blah blah blah after gaining favor buy a sigil and switch. Dunno what tricks A.net has up it's sleeve to get the better things in game.

Once factions comes out, go inspect them with that boat trip. Decide if you like it or not. If liked you buy if not who cares? Nothing really changed except it'll be new for like a few weeks, then it'll be the "same old thing" so to speak...
