To be blunt, offering players the option only to transfer servers will do more harm to low population servers than good, and is a bad idea.
At the time of writing this thread, my server (republic side of Kinrath Spider) has 16 people on the Fleet, not including myself. Doing a search of various zones shows that the server is next to vacant. If and when server transfers are offered, what is almost guaranteed to happen with players on servers like this? They're going to take a look at their character (or collectively as a guild), think about the time they've invested in the game compared to the absolute lack of people to play with, and move to a higher population server. The situation will get worse.
Now, there may be the oddball or two who are already on high population servers and wish to move to a more quiet atmosphere (hey, it happens), and move to a low pop server but let's be honest, the likelihood of this even producing a noticeable effect is next to nothing. Server transfers -alone- are going to make the situation worse for low population servers.
PS- Love the flippant remark about "I'm going to guess you must have come in late", Bioware.
