I took the same approach as your AM did and took a vote on which perks to upgrade. When we got the in-game announcement that the perks were coming soon, I held an open discussion with my fellowship so that they could gain understanding and ask questions about the perks. Playing on Beta helped me better understand the perks, so that I could help my fellowship. Then when the perks were implemented on the live servers I held a vote.
It makes me feel bad for players who have a AM who’s just upgrading whatever perks they feel like. I don’t understand how an AMs/ Mages can go rouge like that and just do their own thing without the fellowships input. It just makes too much sense to me that the fellowship should vote for what they want, like what most fellowships do for the FA. As an AM on my main city my fellowship is trusting me to do right by them, even if it’s a perk I’m not to fond of. If they voted for me to upgrade a particular perk I’ll upgrade it. After all it’s called “Fellowship Perks” not “Archmage/ Mage Perks”.
