According to a new post on the Star Wars: The Old Republic forums, the Asia-Pacific servers will be closed with player mergers heading for the North American server group. Community input was solicited prior to the decision to ascertain the best way to boost server populations. Ultimately, the decision has been made to merge APAC servers with NA.
Why did we decide not to merge the three APAC servers into one large APAC server? We decided this for two main reasons. 1. The issue in doing this is that two play-styles (PvE, PvE-RP, or PvP) would need to sacrifice their desired play-style in order to have one server with a higher population. We feel that it is important that each player is allowed to continue to play SWTOR in their preferred play-style. Therefore, accommodating all the existing play-styles was a primary goal. By allowing you to move to a NA West server, you will be able to keep your play-style. 2. The move to North American servers better delivers on our ultimate goal of providing the best play experience, with the most possible players, long term.
At this point, there is no firm date for the mergers. Read the full post on the Star Wars: The Old Republic forum.
