Just a heads up, if your guild is planning to transfer, make sure you do it before or after you do all raiding for that reset. The support article says it will transfer your raid IDs with you, that’s not the case. It won’t reset your IDs, instead it’ll give everyone a different ID for whatever raids you’re saved to.
Customer service will just tell you “too bad, wait for next reset”, so I figured I would let people know here.
