I definitely understand the pain and frustration behind rerolling (Obviously I am doing it now on the new Oceanic servers) and also countless times in previous MMOs.
But if no one is willing the make the sacrifices for the greater good of the community and for themselves in the long run, yet complain about a terrible population level then I have lost all hope for you guys.
Maybe one day they will allow paid transfers/server merges but until then you guys have to make do with what is available and get together to create a chain of people to head on over to a new server.
Trust me, it will definitely be worth the time invested, you will find yourself in a healthy community, with the ability to find groups, complete flashpoints, operations etc.
The worst thing you are all doing is heading here to /rant all over the forums because all your mates left you in the deep end.
STOP twiddling your thumbs, create a daisy chain thread (if you don't know what daisy chain is google network topology) and get that community you guys are asking for... Its not out of reach and it is not impossible.
