I think it would be a good idea for Clash of Clans to incorporate a sandbox mode for your base, so that way you can attack yourself and see what weak spots you have, as well as decide what could be upgraded next. Also you should be able to attack yourself with the average level troops for your trophy league to make it realistic. This would be a great addition in the next update of Clash of Clans and I hope someone includes this in the next addition.
