The strenght is in the extremely hard to pull CC's. Even with 6+ hogs we were not able to pull the full cc. And not pulling cc messes up most of the attack strategies, unless you attack with Balloons or Goloms. But certainly the most commonly used Hogs attacks will fail.
Take care! It is important to exactly copy the placement of buildings and make an educated guess where Tesla's go. (Always outer layer to distract and destroy Hogs trying to pull)
