I mean the servers named after the regions (Ruben 1, Ruben 2, Elrianode 1 etc...), not between EU, INT, NA and others
1. The matchmaking for PvE or PvP happens only inside that server or across all of them?
Cause knowing this I'd chose the orange or red labelled servers as they're more populated, but if it doesn't change anything then green ones for less disconnection errors I guess
2. It is known where these servers are located? I mean, maybe Ruben 2 is in Germany, Elrianode in Spain etc...
Cause knowing this I'd take a server located the nearest to my region for less disconnections errors
