To be honest, I really enjoy my small server of Fabul. I feel you can get to know people a lot better due to the familiarity of always seeing the same people. I also feel this cuts down on people's "foolhardiness" (trying to be nice using this word) because people might be inclined to be a little more mature and responsible for their actions. I say this from experience of playing ffxi on what seemed to like a HUGE server. From immature shout spams in whitegate, to camping HNMs against thousands of new people all the time, I like my small community.
