I might be a bit theatrical about the topic, but that's because i've seen too many mmo's eat it from a failed merge or suffer heavily from performing one from then on out.

It's just that I don't wish to see this game so easily flushed because of a small problem.

Being a computer tech I can tell you that even with flash based memory, you can only read one way and write one way. So unless they were pulling from another set of clone servers, you're only able to do one task at time at a time. Same thing applies when you try to install and delete something at the same time.

That's just the limit of technology
