As far as I recall there was an immense amount of pressure from the Oceanic community to make BioWare open local servers there. It's very unfortunate that players there now ask to be able to transfer back to US servers.
I agree, it's unfortunate, but having a ghosttown for a server impacts the enjoyment of game play in many serious ways .. The GTN economy is dead, the warzones take a long time to pop, it's almost impossible to find someone to play along with for HM OPS during the day.. (some of us are shift workers and don't get to play in prime time).
Merging the three oceanic servers would go some way to alleviating this issue.
