New Currency stop DE troops
I feel that there is enough DE troops already in the game and they have ran out of ideas( probably why last update didn't have one) I'd rather have a new set of troops set up than somthing forced out. Here are some routs they could go.
Animal troops
Insect troops
Water troops
Or have all three types as nature.
The water troops would be only ground troops, insects would mostly be air, and animal would be both.
With new currency and barracks they would have a new hero (somthing not lethal that would shield defenses and troops. Heroes protect so a hero with shield powers would make sense.).
