Just started on TalonRO last night. had about 1.2k players. seemed to have a lot of active players for a private server, and also because I assumed RO private server community was dead.
Seems like a good population, however I really dislike it because you can get godly gear (ie god equipments, MVP cards) from donating/doing events. They have separate PVP rooms and WOE which restricts the godly gears, but I havent checked out hows the population in those.
Unfortunately it seems that the other servers are dead. Based on RMS standings, 1st place (TalonRO) has 1.2k players online, 2nd place (heRO) has 200 players online. Thats a big difference. I guess I'll stick with Talon for a while
