My Mainstory Quest is in Dravania, and I havent been able to play in this zone for 3days now because of insane high lag! Also spoken to other players in the zone who have said the same.

I don't wanna pay for a service I cannot use. Why should I even play this game if I cannot even progress in the Main Story to reach the Expansion I just bought?
Is there some way to get a refund?
