Wouldn't an attack from the left or right flank be more effective? (1) Higher lvl people usually have more success attacking me from those directions. I'm not convinced a direct attk with so few units would pull off the effect you are looking for. But I guess it does come down to how you use those units (2) LOL If your goblins did manage to get into the center as you plan, they are getting hit by 2 motars (should be 3...one is upgrading), 2 WTs, all 5 ATs, all 4 cannons, and if my guess is right, 2 HTs. I'm also guessing a few spring traps will rain on your parade

If the max you can steal is 180, I guess I can see you getting away with two-thirds of that...maybe.(3)
Love the diagrams by the way.
