During the stress test there were several low population servers.
The stress tests were a whole different animal to the initial BWE - even Jade Sea seemed less crowded than usual. Petrified Forest might put some people off since it's the "unofficial" RP server for Europe, although I don't feel it'll impact our experience too much. It's also a bonus from a personal perspective because a bunch of my GW1 alliance friends will be there.
But in the interests of providing choice (ANet has added some new servers) - here is a list of servers not flagged as GER/FR. This is all based on the info
off this link - I have no idea how accurate the info on it is though. There are a bunch of new servers, but no guarantee that they won't be assigned a language down the line:
Kodonur - Seems a lot of Polish are hopping on that one
Gandara - Lots of UK peeps, couple of others
Blacktide - Polish/Russian Majority
Istan - Multi-language - very little Eng from what I see
Vabbi - 4chan chose this one, so not my preference
Kourna - Not flagged as FR, but seems to have a lot of Frenchies on it atm
Fissure of Woe - Italian/FR
Underworld - Multi-language, but mostly ITA and POR
Ring of Fire - Mostly Romanian
Far Shiverpeaks - Dutch/Scandinavian
Petrified Forest - Seems like the choice of the moment
Gunnar’s Hold - Seems to be a new server
Olafstead - New Server
Boreal Station - New Server
Jaga Moraine - New Server
