So upgrading this need a lot of resources while the storage capacity is small only 5k for buying with silver coins not CRYSTALS.

The game push you to buy CRYSTALS or you need build 10-15 pcs (@5k each) storage warehouse and consuming a lot of area.

Need a sale again on storage warehouse, I miss this sale on event Halloween (if not wrong).
