Not sure if anyone at CC even reads these posts anymore, but I'd like to suggest a change in the cool down period for moving Mayor's Choice.
Considering end of weekly raid as a starting point (where MC has likely been on Castle all weekend), I think most Mayors are moving it shortly after. With the current 24hr cool down, that means that a Mayor is only able to move it then, then again 24 hrs later on Monday, and again 24 hrs later on Tuesday. Wednesday night moves are a write-off, because with the current length of cool down, you can't get it back to Castle by start of next raid, so it sits on the Tuesday night selection for nearly 2 full days. Pointless.
With 25 players in a city, all of whom have different priorities and requests for buildings to discount, three moves per week is somewhat limiting. If the cool down period for moves was, say, 22 hours, Mayors could squeeze in a 4th building weekly, and still get it back to Castle in time.
