I was an Archmage committed to my own standard and charter, and I am stubbornly loyal. I was on the new server, so everyone in my neighborhood made a flag and wrote a charter, and we were lots of little nation states. Then we saw the advantages of merging. I agree with Lyleth about learning from other fellowships in other servers. I was invited into an amazing fellowship on a different server, and learned how things could be, and weren't in my fellowship. I took my two most devoted fellows, turned over the Archmage powers to another member who was always online, but not really progressing, and hit the button to leave. Oh, that was hard. Yes, they have changed the standard, and a bit of the charter, and reassigned archmage, and all sorts of things while I have been gone. And I think of them from time to time. But I would have quit the game entirely if I had stayed.
Do consider joining a more active fellowship. You might even need to try a couple to find a good fit with like-minded players. Exchange emails first. Encourage your Archmage to consider long term goals for her own game. Does she need the title to achieve those goals? If you are on one of the new servers, things are pretty fluid in the beginning, but settle down, then it is harder to find a good fellowship.
Best wishes for a fun game.
