Paragraph 1:
Avatars will be cosmetic only, there will be no returning avas to citadel, there will be no recalling avas to citadel (that option will be removed also - it will become a control stone used for other features), & clans will not be limited to 3 people having the appearance of an avatar follower.
Paragraph 2:
Having an avatar follower will provide no benefit, it will be cosmetic only.
Having the Avatar Warden job will not be required to have an avatar follower for the reason above.
Paragraph 3:
Clan admins can customise the clan's avatars' appearance at the control stone.
This will be the same as it is currently.
I can't remember if there is a permission for this specifically.
If there is, it will be whatever rank you set it at (minimum will be Admin).
If there is not, it will be any Admin rank or higher.
