Blizzard is not going to merge Skyfury or start doing auto-merges. The most you’ll get is free transfers off. What Blizzard has been doing is offering free transfers off servers and later deleting those servers. You’d probably be offered free transfers to Eranikus if anything. This is just the reality.
You can suggest free transfers in this thread too: Character Transfers Update - WoW Classic / Wrath of the Lich King Classic Discussion - World of Warcraft Forums (blizzard.com)
If you actually want to unsub that’s fine. Put your reason in the box.
