Glad to hear that clans are getting more focus for updates in the coming year
I have to agree with everything that's already been said, but I'll list these as my top 3:
1. Avatar recall / tracking¹
2. Recording all clan members who've capped since the last build tick²
3. Muting individual clan members³
¹
I would specify whether to just have a notification in the clan chat channel or to have a list display of who last summoned an avatar, but the latter would be redundant with the recall feature added as tracking down who logged out with one would no longer be an issue.
²
This feature would free up the hassle that comes with rewarding those who contribute to citadels each week, especially clans that enforce mandatory citadel work.
³
I personally can say that this is a much needed feature. Sometimes a clan member has a "bad day" and needs time to cool off (mute), rather than remove talking permissions from everyone at that rank & below, including guests, or even removing them from the clan entirely.
And if I could add a 4th, I would like to edit the buffs on an Avatar rather than needing to rebuild the entire habitat. (Not a priority since having a 2nd and 3rd Avatar is possible, just would be nice to have if it wouldn't take away from other, far more important, updates)
The member of my clan who originally built our avatar habitat (long before I joined) didn't know what he was doing, to say the least, and the only useful buff our first Avatar has is the Skilling Bonus, followed by Auto Ort and Familiar Faces, neither of which are ever used.
