First Great Concept - It is long overdue
Some suggestions:
1. Structure the inventory window to mimic our in game inventory window, with separate tabs for buildings, consumable items, and GB Blue Prints.
This would make it easier to locate an item we wished to breakdown.
2. Add the age of the item next to the item so we know which ones we are offering - in my regular inventory I have, for example, Faces from all ages - so I would want to breakdown the oldest ones first and remove them from my inventory. The same with Tribal Squares - I would want to breakdown and remove the oldest ones first.
3. Add sort buttons (Think this was already mentioned) to be able to sort by age, value etc.
4. Change the 2 hour limit to 1 hour. The 8 and 24 hour work for those wishing to do something over night or during a work day. But 1 hour would work better
since most players can then set up a breakdown, then go off and do GE, PvP, GvG or collect their city and be all done with it in an hour and ready to collect their breakdown amounts rather than having to wait another hour just to collect. 1 Hour is more in line with the production buildings output.
5. Add the ability to breakdown GB Blue Prints - Many of us will never build the Colosseum nor Notre Dame and would love to breakdown those BP's for something useful. Additionally, those of us with high level ARC's that help out others have thousands of ARC BP's just sitting in inventory that will never be used. And I am sure they are taking up valuable space on the server. Why not let us break them down and get them off the servers to free up space?
