$ New Troop: The Goblin King $
So I was recently playing single player mode and then realized that I have almost completed it. I was thinking there should be something greater in reward rather than just loot, "I can get loot whenever I want".
Most players don't even bother wasting troops on single player mode, but if you were to get a new troop out of it, it would become a motivation to complete the map. I now introduce to you... The Goblin King! Obviously his hit points would be greater than normal goblins, and when raged he summons 10-15 goblins at a time?
This troop would also not need dark elixer, gold, or elixer to buy him, "Since he is your reward for completing the single player map". To upgrade him large amounts of gold would be needed.
Let me know what you think!
