I think there is some truth to the servers dying and BW needs to start seriously considering the possibility of merging servers to keep them populated.
As of now, on my server (Kath Hound US - East Coast), I am routinely one of the only players on the higher level planets (usually about 4-5 players) and it's near impossible to do any of the heroic quest b/c there is no one to group up with.
I still love the game and continue to play it, I just loved it a lot more when it was easy to find at least 3 other people to do flashpoints and/or heroic quests.
