It is a fact that players usally lure out CC troops and then take them out. What if some CC troops, say 5, were put on top of the CC to defend it and the surrounding area ? The CC would work as normal but people could request for ranged troops(like wiz,arch or witches) to defend the CC and the surrounding area. Those could not be used in attacking only in defending. They would just be regular troops on the CC. The thing that would make them special is that they could not move and that the CC would have to be destroyed first before the troops on top could be killed.
I like this idea however that troop should be destroyed with the.clan castle! You have a castle cave in under you that would be kind of hard.to come back from! Plus the whole time the CC is being attack they have the troop on top attacking!
