So my clan tells me to build only spies for my kningdom because it would give me much more gold? Is this true? If so may I please have an explanation of how this works? Thank you!
it's all about allies bonus. for some reason (that was never properly explained to me) spies increase your ally plunder bonus when you attack, the same way that troop buildings do. (usually) by slightly more. spies are op. it isn't just about how much you earn. spies have the ability to attack troops AND spies at the same time, while troops have no option against spies at all. spies can be used to completely clear an enemies gold, because they can continue to steal once the enemy's spies are at zero (as long as their troops are up and they have gold out) so yeah. you need a troop building; but building nothing else but spies is a common thing.
