I suspect that Bioware might have signed contract with service provider for these 3 servers for running within certain period, while they thought SWTOR would had e a huge demand with enough ppl to fill up at least 3 servers for years.
Although now is clearly not the case, they have to stuck with 3 servers at the min.. Whether they keep the servers or not, rental payment must continue. Hence, Bioware is hopeless on this issue as well as like us. LOL.
Even if that is the case, they can pay the rent while allowing transfers between the three APAC servers. This way we can do the work ourselves, get organised and migrate to one central server. We actually wont be needing super servers to support the load even with all three servers combined. lol
