more resource useage.
E.G.
- Catpalt need stone resource for each battle. because they through.
- Archer needs Wood and either Stone or Iron for each battle. Whats their arrows are made of?
- Infants need Irons to maintain their swords. (if rusty or brade broken, need replace)
- Hourse needs Irons for their feets.
- all troops need iron for maintaining their armers and shealds.
these things above may reduce warehouse over-flowing and stop players to feel disapointment for wastage.
