Its so tiring when you have to look at your attack log to see which and how many troops have fallen, in order for you to train the exact composition of your day to day army
I'd like to propose an idea about presetting troops that you usually use for each battle, when each battle is over, you can choose to replace the fallen troops in the barrack with just a single button. So when the barracks finish training troops your troops will look exactly like the one you made before you begin the battle :D
