The problem is not that they split servers, the problem is HOW are they splitting them, it's like they didn't think at all how to do it. I don't know about the NA data centert but at least in Europe the big worlds are all together now in Chaos and the Small worlds all together on Light, what does this means? Light is gonna have lower queues, less PF movement, less people, less raiding.... and people on future Light DC server is already planning on moving to Chaos DC, so it's gonna be even more empty.
The new DC is not out yet and they already killed it!
