Reduce percentage of damage taken when having barracks, builder huts etc. destroyed.
I say this because lower level Town Halls don't have the size to keep everything close to their defenses. By this I mean I have my important buildings town hall, clan castle, gold and elixir storage etc. within walls and protected. However I constantly get nickle and dimed for trophies by player that drop archers and destroy the smaller buildings on the outside and never make a dent in my defense. It's a good strategy but if I'm going to lose trophies because over 50% of my village was destroyed, it should be because I lost more then barracks, army camps and builder huts.
