I don't have much server loyalty at all, and hop around every week or so. But what I do recommend is NOT joining heavily populated servers. 9/10 times, the high-pop servers get unintentionally grief-ed by mass tunneling and chopping without destumping.
I have had lots of fun playing on low-mid pop servers that have a loyal and active community and GM's that are not in GM, but only in GM when called to service by the community.
Hope this helps.
