It would help a lot if you have that option....sometimes player won't have enough money to purchase and or pay 640 gems or 300 gems for full completion of a defense or a strongger army but he/she might have 10, 20, 25 gems to speed the procces of that which they so anxious need or want...for the lab and some buildings of 3, 4, 5, 6 days is really too long.👍
