People to come back? No please! There are plenty of ppl already. My server is a real mess and its always full with 4-5 Fleet , Makeb , KDY , Tython , Dromund Kaas , Korriban , Coruscant instances.
Don't know what server you're on, but on my server, prime time means 120 people in a single instance of Republic Fleet. Never seen more than 10 people on any planet above level 40 (except during events).
So, yes, I sure as hell, would like more players to join the game. If you REALLY have such problems with too many players, then please transfer to literally any other server.
