-- [ ] Each class can be assigned to at most one player at a time, and a player can hold at most one Tyrant-side class.

-- [ ] The Tyrant cannot assign a class to the Tyrant, an opted-out player, or another ineligible player.
-- [ ] Reassignment removes the class and its bound items and effects from the previous holder before granting it to the new holder.

-- [ ] A class holder is reminded of the assignment and its controls on login.
-- [ ] All class assignments end when the Tyrant's reign ends.
