I am liking Icegag's approach on the idea it's all about the orientation of something, previously it has been I can do this, and the new aproach is someone else can do this.
If we are talking about improving ones game, another option is to have a practice attack after clan wars has ended, ever got 49% and missed the TH - well how about when war has ended anybody with 0 Stars attacks are allowed to have a free practice attack (- troop train cost) on the same layout to see if they can improve their attack strategy.
I am not a fan of testing your own defences but you can learn from one war how good your base is that is enough, everything is a learning curve, and to some degree you can also test it out in multiplayer aswell.
