Booby trapped gold and elixer storages.
So I was thinking why is it so easy to break into my gold and elixer storages? Surely I would have them booby trapped with a small explosive device or poison. You could begin the trap at level 12 and increase the damage at 13 and 14. It would give maxed out players more to upgrade, allow us to hold more gold and elixer, and make it harder for ppl to loot. And add a major twist to looting! You can also make a new troop, the Thief. Or even better allow the goblin to disarm to trap at a new max level. You can have the gold use the explosive device and the elixer use poison. And have them arm like a normal trap with rearm all. Great idea right?
