An ArenaNet blog posted moments ago details how servers will work for the beta and (quite possibly) the future. The price for changing home servers is going to be 1,800 gems, but otherwise it looks like players will have near full reign of whatever else they do as far as ‘guesting’ on other servers!
Server names for EU and US were also announced, which is great for those coordinating with friends and guilds to get on the same server for World versus World PvP.
The US servers are as follows:
|Anvil Rock||Blazeridge Mountains||Borlis Pass||Crystal Desert|
|Darkhaven||Deldrimor||Ehmry Bay||Eredon Terrace|
|Eternal Grove||Ferguson’s Crossing||Fort Aspenwood||Henge of Denravi|
|Isle of Janthir||Jade Quarry||Kaineng||Maguuma|
|Moladune||Scavenger’s Causeway||Sea of Sorrows||Sorrow’s Furnace|
|Steamspur Mountains||Tarnished Coast||Vasburg||Yak’s Bend|
And the EU servers are listed below:
|Abaddon’s Mouth||Augury Rock||Aurora Glade||Blacktide|
|Desolation||Elona Reach||Far Shiverpeaks||Fissure of Woe|
|Fort Ranik||Gandara||Istan||Jade Sea|
|Petrified Forest||Ring of Fire||Riverside||Ruins of Surmia|
|Sharp’s Corner||Underworld||Vabbi||Whiteside Ridge|
