Other Suggestions

Ive been thinking of actual underground mines, ive also been thinking of introducing water based troops and designs moats and lakes etc, also for example a kind of troop that digs underground to attack certain things, also introducing Vampires, Wearwolfs , and also a type of troop called the Devil that can shoot poison spells, and a new spell that sends swarms of health damaging things that could be used on cc troops, for example a swarm of Minions , Barbs or Archers are released, and you can choose what types of troops you want to be deployed in the ring depending on size of cc and how many housing spaces, plus also a flying unit that can drop webs nets,etc from the sky to immobilise defences temporarily, plus can you make higher level troops, e.g Witch go up to lev 5 and also Hogs and Loons to level 7 like Arch Barbs and Giant's. I also like the idea of a Goblin king but their supposedly the enemy shown on the goblin map.
