Just like the layout editor, but for your troops. The troop editor gives you the option to store up to three different troop compositions that you love and primarily use. This will be great for resource farming and trophy farming were people tend to use the same compositions over and over. It will not effect wars as much due to being an effective war raider you must build compositions around your enemies base to guarantee the stars you want.
A feature that allows you to re que your previous composition like boom beach has would also be a great implement, and something of this nature shouldn't take to long as it has already been done on a previous supercell title.
