I'm going to talk to my LS and some other folks around my server who I like playing with and we'll pick a number together. We have a month to come up with a consensus. In the coming weeks folks will start creating classifications for the server numbers (PST, EST, Euro, South America, and even play-types such as RP). This will make it easier to decide. Since the servers are just numbers for right now, I have no idea where I'll end up.
