Can definitely vouch for Balmung.

Transferred from a different server myself because I wanted to be able to PUG endgame content without having to commit to statics, which is not an issue on Balmung.
People don't mind helping out each other here, and the majority are pretty respectful. I'm slowly trying to convince my friends on the other server to transfer, too.
This is a server that you can log into when you have some time to kill, and actually get some stuff done (PF is almost always active with Primal/SCOB raiding).
