Random question about SoR I didn't find an answer to anywhere : what would happen if you try to transfer and faction change a GM toon ? (specifically as part of SoR perk - this is not the FAQ about server transfer)

I'm curious if you would get an error it's not transferable (like for a normal; non guild; server transfer);

Would the guild move for free (that'd be nice);

or would the GMship transfer to next rank (like when you're not logged in for 30 days)

(did anyone try)
