Is there a popular server I should join?

The game lists server population when you go to select it so if you are looking for a populated one use that. If you are looking to join up with others from the GB community I would say that they are on the NA Mind Trick server because of the guilds. My understanding is that even from overseas the lag isn't bad playing on a NA server.

@DexterKid: The GB people are indeed mostly on NA Mind Trick. Lag is not an issue. I play with a 150 ms latency and this has zero bearing on the gameplay.

However is certainly has an impact on how you will find groups to do stuff. But it's not terrible since it's east coast.

Most of us UK folks play on Mind Trick NA.

I have a toon on Mind Trick and didn't notice the lag until I made a character on The Ravager in the EU servers... so much smoother

I'm on Shaltin Tunnels, RP server.

I play on another USA server but so far on all USA servers I average 100 ms to 120 ms at most. But the GB players are mostly on Mind Trick.
