Server transfers
Not a one time deal, you can do it as frequently as you want (until they implement guesting, at which time you have to pay).
However, any points that your guild has banked (I think they’re called loyalty points?) are lost on a server transfer. However if you to transfer and transfer back (like to group with a friend on another server), the points will be there when you come back.
Yeah, you can move as many times as you want at the moment, but they will be ending that at some point after which transfers will cost gems.
I believe you lose any influence your guild had if you shift to another server. I’m not sure about guild upgrades you’ve already purchased – someone else may be able to answer that?
And read the rest of the thread too, new information from other players were posted.
