Goblin King for the 3rd Hero!!

Let's face it, there is little motivation to complete the single player mode by collecting all 150 stars. ESPECIALLY when your only reward for accomplishing such a achievement is a measly 20 gems. It is a bit insulting if you ask me, considering you get 30 gems just for cleaning your base from trees and rocks. I propose that a 3rd hero be introduced for completing single player mode, that being a Goblin King. Goblins in general have a bad rep, and almost know one wants them donated. When I first started playing this game I thought the goblins would attack me more often and the last campaign battle would be much more in general. it was a huge disappointment to say the least. Let the Goblin King revive the glory of Goblins everywhere and make beating single player worth it!

Proposed Requirements and Hero Details:
To unlock character- complete single player campaign by getting all 150 stars
Favorite target: Town Halls and resource storage units----(it would not have a insane amount of health, so with out back up troops this could prove to be risky)
Special Abilities- similar to barb king creating goblins to help in battle

I also propose the health should be the same, if not a little less than that of a Barbarian King
Also when it is attacking its favorite targets- DP are the same as a Barb King as well, but will receive a 25% damage boost exclusively on Town Halls and Resource storage units.

2 heroes is enough and a hero that goes for a th is OP.
