Well.. I'd assume most PvE players are in a similar situation to me.

I chose Cenarius, because the majority of my friends who were quitting Everquest had decided on this server. Most of them don't play anymore, but I've made new friends who are here on this server. So, while I'm not opposed to playing with other boxers, I don't really want to leave my server either.

The other consideration, I have 30 odd toons who I use for gold generation, and that many server transfers would be prohibitive, even if all my friends decided to move to another server too.
