Mercenaries

Wouldn't payed soldiers be a great idea? There would be a new building that could be rebuilt. Then you could enlist mercenaries to help defend your base from an attack. They would be able to e used once then would have to be re-enlisted. The more you upgrade their building the more mercenaries you could hold.

clan castle troops on defense already fulfill this requirement.

As hawdog said clan castle and its a tad op budd

Good idea, a lot of the time I have spare gold and this would be a great way to spend it.
