Leaving Siren help community problems?

[TorqueFork]

I know aboslutely no one on Siren anymore. Just feel like I'm floating around with no goal. With Odin and Bahamut at the top of the most populated servers, will I find a good blend of old and new with either? Maybe more active community?

I'm leaving shiva for similar (and other) reasons and will be headed to bahamut. my friend says its great there
