New troop, the troll

This is my own idea and did not get any inspiration from any other posts.

This beast of a troop will knock down anything in it's way, even it's comrades, just to get to the thickest kf fights.

Name of Troop: Troll
Training Cost: 500 D.E
Training Time: 45 minutes
Housing Space: 30
Damage per second: 50-200
Hit Points: 3,000
Movement Speed: 12-24
Favourite target: Any
Level unlocked: town hall 10
Specialty: rage. His dps and speed will increase as he takes more and more damage.
Description: the troll will bring be a different troop compared to others. As he takes damage from defenses, he will change colour from green-purple-red to show that he becoming a raging brute. As he nears red, he will target friendly troops that come within a 2 block radius of him. This would prevent mass troll raids as they would end up killing eachother. Once he hits 1 health, he will be at his utmost bezerking rage and will not die for a few seconds. This duration will increase as he is upgraded at the laboratory. He would make a great tank but difficult to use and would take a bit to get used to timing when to put the rest of your troops down.
