I am sorry about your besaid experience hasn't been what you would like. You never gonna know where people are from. No one wears flaggs for region or country.
I have been on 3 servers and Besaid by fae has the largest English speaking population in my opinion. What are you looking for people for? To XP party? Help for other stuff?
How long were you logged in an active on the server?
Did you shout for other for whatever your needs were?
Did you use the search function and put in a note about what you needed. Did you go to the server area or new player area of the forums for initial assistance and/or guidence?
