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.
Your post makes zero sense. Even if they're locked into renting servers out, why alienate large numbers of subscribers and reducing their revenue by forcing people to play on dead servers?
