I was surprised by a lot of the information I found when looking at my servers. Going in I assumed that Earthen Ring was going to be the most populated server I played on. It turns out that Kel'Thuzad has 16,588 more players than Earthen Ring which is almost the total number of horde players on Demon Soul. The relationship of alliance to horde on Earthen Ring is much closer, at .92 A/H, than I would have thought. On Demon Soul there are only 4,665 alliance players to the 18,238 horde players for a whopping A/H ration of 0.26. That's pretty much 4 hordies for every alliance scum.
I found out that Demon Soul really is dying. I compared the 4 servers that I played on (and the newly selected a 5th) to see how they compared. The highest population server that I currently play on is Kel'Thuzad with 99,098 characters. Demon Soul by comparison only has 23,039 characters. As you may know, Demon Soul is the realm where Chuckem (my only level 85) character is and is the server which I play on the most. I just recently rolled an Alliance, Human Rouge with my guildies who wanted to try the other side. Their move to Kel'Thuzad was also influenced by it being a popular Alliance and PvP server. These statistics show how much of a difference there was in player base.
I decided to populate the Darkspear server because they were the highest populated server that was not locked at the time. Darkspear has 101,595 characters with 64,626 alliance toons and 36, 454 horde toons. That's a 1.77 A/H ratio. Accepting the thought process of my Morningstar guildies in wanting a server with a lot of activity I went out and found the highest player-base I could find. And since I'm doing the 2012 in 2012 challenge I decided to roll 10 new toons on the Alliance side there. Because 10 is also the same number of classes available I made one of each class. I have only leveled 1 of them to level 4, but I have made all 10 to reserve the names and map out which class/race combinations I wanted. I'll write another post on that later this week.
Here is the data I pulled off of (http://wow.realmpop.com/us.
