Were you the GM who originally created the guild? I ask because I’ve only ever seen a guild handed back once, and it was to the creator, not someone who was just a previous GM. And too, for future reference? You could have prevented the dethrone and left no one at a rank who could take the guild like the position you’re in. Once the guild is handed or taken over, that person is the GM and has every right to do what they want with the guild. While it’s usually pretty cut and dry that Blizzard GMs are hands-off in these cases, there are sometimes exceptions made for the creator of the guild who was dethroned.
There are no GMs here on the forum, so you would have to submit a ticket if you were the original creator of the guild. I will warn you that ticket times are a little crazy right now (about 5-7 days).
