Well, clearly the warg is out of the bag on creep transfers.
You guys have been asking us for months for the ability to transfer your creeps to other servers, but that tech was not built into the game and we haven't been able to offer it as a service. The tech is there now, but it hasn't been thoroughly tested and we still don't know what all of the ramifications are, not just on your characters but also the halo effect it can have on other internal projects.
Unfortunately a few transfers happened before we were ready to roll it out. We just can't do any more transfers until we're done working on the tech and have tested it. It IS being worked on - we've heard you guys, we know you want it! - but for now, we can't in good conscience continue to offer it as a service when it hasn't passed QA and could potentially bork your characters down the line. Until we know what all of the edge cases are and how we address them, we won't be offering this as a service.
We do know that, for instance, if you don't have a freep on the server you transfer to, you have to level a character to 10. You also lose all of your destiny points. Those are fairly minor. QA is looking at what else it could cause, either on the character, the servers, or our databases. This is a much lower priority than Book 14 and Moria, so we don't have an ETA on when testing/development on creep transfers will be complete; just know that it's on the radar and will probably happen at some point. This is something we just didn't want to announce and talk about until we knew for sure we'd actually be able to do it.
Thanks for your patience in the meantime!
