IMHO the reason for the new DCs and server shuffles is likely an attempt to avoid creating another "Raubahn or Pippin EX" scenario again during the 5.0 launch. We know for a fact that the reason these things happened is due to the sheer volume of players congesting to those instances and clogging each DC's instance server. By creating a new DC and lowering the number of servers per DC they can ensure that the volume of people hitting those instances at the same time is manageable and does not cause the instance server instability we saw during the 4.x series at said choke points.

This is an attempt to bolster the serviceability of the instances, unfortunately there is a sacrifice to go along with it, but if splitting the community a bit more ensures that I don't get stuck on MSQ 10 quests in on launch day, I'm all for it.

Some of us do work in IT and, while we may not have explicit insight into XIV's server architecture, we understand enough to make educated guesses about the kinds of problems they may be running into based upon the symptoms and issues the system is displaying.
