I’ve been the only active player in my guild for about 3 or more expansions.
GM hasn’t been on for 4 years.
1 officer logged in over 6 months ago when the latest expansion hit to see how dead things were.
I’m not of a level to dethrone the GM using in game auto options.
I can’t see how to open a ticket to request I am promoted to guild master?
I could leave but Printemps feels deeply connected to the guild name now as it has been part of their identity almost since starting Wow back in Wrath.
If you are not of a level to dethrone, then there is nothing to be done. Blizzard designed the system so that Guildmasters can have control over their guild structure.
If you have any way to connect to the current guild master or officer that can promote? They can of course log in and bump you to a rank that can dethrone. That would be an option, depending on whether you have some way to contact either.
