Q:
Good server?
Well, there can be several gauging factors when it comes to server choice:
- Guild size, language and main activity: http://www.gw2guilds.org/guilds
- WvW ranking: http://mos.millenium.org/matchups
- Server language (official or unofficial)
For the “unofficial” server language, you can either do a forum search or check gw2guild and list the guilds by member count. - Player number: The more, the better (usually)
- Roleplay aspects (e.g. Tarnished Coast)
Since server transfer is no longer free, you should definitely choose a server with high population as primary priority and one or more of the above points as a secondary factor.
The gw2guilds.org site is not always up to date so if you see a guild that you want to join or you chose the server because of them, you can always ask the community if they are still on that server.
if you want hard core wvwvw(no fun after a week) pick one of the top servers in this list:
http://mos.millenium.org/matchups
if you like pve and decent wvwvw, i recommend crystal desert: because unlike other servers you actually see people other then in lvl 80 zones. Plus go wvw is alright not the best but people play at content rate. for example: most wvw is packed on fridays and almost empty later in week. crystal desert had same flow of people all week. i like it cause i do pve and dungeons and sometime wvw so it offers all.
