I would vote for finding a FC or LS that fits your style. I don't know how much changing servers would really help in the long run, as this game really does seem to foster a solo/silent play-style. My guess is that other servers are pretty similar.

Sadly, you're stuck on Balmung for now if you want to keep your original characters since legacy servers aren't open to transfer yet. I know you said you're not looking for friends, but I do think the social aspect of this game makes it a lot more tolerable and fun.
