New Dark Troop Idea

My idea of a new troops is a bulldozer. This troops would act like a continuous wall-breaker, which just walks in a continuous direction, until it collides with a wall, and then it would ram the wall and destroy it and continue on etc.
For overall stats of the troop, the health points could be 5000 hit-points and the movement speed could be 10, so a slow unit and could cost 600 dark elixir. Once the Bulldozer has died it would explode with 500 damage. The standard damage it would do on walls could be 800 damage per strike. It would take up 24 spaces in the army camp.

this is way to OP, wall breakers would never be used again if this got implemented.... so OP
