If it's like World of Warcraft, where realms just pop up on release with no forewarning, then you could decide it on a numerical value.
Like, for Rohan, I'm likely going to join the middle server, rounding up. That way everyone knows as soon as the game's released that Noble Phantasm's on server 2 if it's out of 3. If there's 6 servers, then we're on server 4.
Btw Karamazi, I really like your avatar~!
