Guild Wars 2

Is anet planning making new pairing or world links tomorrow?

No, its meant to be for 3 months

The pairings are done manually and not via algorithm, so they can change it whenever if they feel it’s not working out. That being said they don’t want to have to do it too often. I assume the 3 month figure applies if they feel things are working out reasonably well and is done more so for variety of matchups and rebalancing as servers gain/lose people.

I expect pairings to change after/during the beta period. It is also possible Anet will abandon whole idea.
