According to a report from IncGamers, there are no plans close any other EU Warhammer Online servers.
"GOA, European publisher of WAR, has no plans to scale back the WAR servers," said a spokesperson. "There is an ongoing optimization process that deals with efficient distribution of players between the servers, which is designed to ensure all players get the best possible experience."
Merging two low population servers into one works, because many quests in WAR require a high level of players to accomplish a task - like sacking a city.
On the flip side, the fate of low populated US server Ostermark is still up in the air at this time.
