Clan Castle Troop idea.

Hey there!
I just got an idea for your clan castle troops in defence!
You know how when you click the info button on your CC, and you can see the troops you have in there? Well there is a red button which can get rid of the troop, but in the other corner, there can a blue button which will allow you to choose where you want this troop to 'hang around' once it has been activated.

Positives:

Adds a new level of strategy
Better defence

Negatives:

Harder attacks
Killing CC troops would be harder

Maybe if this idea makes attacking to difficult, there could be a way on actually seeing where the troops are going to go before you attack - like a little blue ghost (of that troop) in that area. But that's only if it makes it too hard. BTW, if you set this for a particular troop, it automatically saves so you wont have to reset it each time.
