To reduce the suffering of the losers ,I propose a new mechanics.
After the destruction of all the buildings form ruins ,and possibly the whole of claym as the ruins of the monument. To restore your castle will no longer need to build it , it is enough to make half the resources in the ruins . The first time the ruins can be restored in 3 days , the second time in a week , the third time in 2 weeks, etc. This will allow you to have fun in attack and reduce losses in defense , making the game easier.
