World Alliance Update

Seems pretty simple in theory, but I think it'd actually be tough to reverse to me. Off the top of my head, I see cross-allied server marriages, guilds (alliance by extension), and families as potential issues. You marry someone who's in an allied server? Do you just end up not married anymore if the servers are separated? Have to sort through all of that, give compensation as necessary. Then, family I don't see as as big an issue, could just delete the members from allied servers, not having a family isn't that big a deal. Then guilds, there's only one guild leader, one alliance leader, do members just end up in the same guild, but now without a guild leader? Are the guilds that are allied in the merged server environment still allied in the separate servers?

It's just a lot of stuff to have to sort through. Once people mingle, I would think there's no going back.

I was implying more of a rollback-type reversal. You are correct in that your proposed scenario would be difficult to manage - though perhaps not significantly more difficult than the initial merge of the servers already is.
