What we need more than reduced transfer prices is a server merge! I don't know about other players, but I have 19 characters on The Bastion ALONE, and at least two on all of the other North America servers. Even reducing the cost of server transfers would mean I would need to invest HUNDREDS of dollars into transferring the characters I play to a more populated server - and I know for a fact that other players who are in the same boat as me would rather move on to another game than sink that much money into being able to continue to play a game where the major issues are not being fixed.
I have been playing this game since launch, and NEVER have I seen the population of any of the servers I have been on as low as they are now. I never see more than 30 people on either the imperial or republic fleet (during prime playing times) anymore just on The Bastion - and it is the same with a few of the East Coast servers as well. Having the lower cost of the server transfers is what has caused the mass depopulation of many of the servers and reducing the cost again will just bring about a greater depopulation of these already DEAD servers. For many of these servers it is nearly impossible to get a que pop for operations, pvp, ranked pvp or galactic star fighter, and when players are on a server where they can't do anything they will stop playing. The only real solution is to do a server merge, especially since now it doesn't really matter what kind of server you are playing on since players have the option to sit in a PVP or PVE instance.
