I'm on Odin and enjoy it. I'm very casual due to having a 2 year old and a newborn, but I see plenty of activity on PF and shouts looking for more for things. Zones and towns you always see people too, not sure on how populated the lower level zones are, but I do some mining in Northern Thanalan sometimes and there are usually FATE parties going on there at least.

DF queues are currently messed up. Get 50 min queues even as WHM but I hear it's like that most servers since patch.
