As a guild leader it’s pretty difficult to see if somebody is from the server my guild is on or not. The only two ways i can figure it out is if i ask them or invite people in wvw. What I suggest is that you could introduce a name tag or an abbreviation to show from which server everyone is. So it might say like Agus Fìrinn [LNH] and if I click on that person it will say
Another option would be to make the 5 racial cities and LA server specific maybe. Guilds could do their recruiting there and role players could find each other.
