Looking for an active EU server
While I’m on Tarnished Coast, a NA server, I know that there are quite a few guildmates of mine who are on Gunnar’s Hold.
What hours are you playing? If you tend to be playing when most people in your time zone would be asleep or at work, you may want to consider transferring to a server with an active population when you are active (even possibly non-EU – if your connection is decent you shouldn’t notice any lag).
You could also look into which servers have guilds that are known to be more social and helpful. While Legion of Honour is cross-server, you could go to the Guilds subforum of the GW2 forums and see who’s recruiting.
Hope this helps!
