Hello,
Here is a idea for a new building.
A storage building. When your create new troops, you could choose if it's for the usual military camp or the storage building.
This building with his own capacity (depending on the level) could be only used to give troops to your mates for clan war or normal attacks (for their clan castle).
This way, you could prepare your own attacks and still be able to help your friends and your clan.
Greetings.
