[Avatar: The Last Airbender] Why did the Fire Nation need a Drill to break into Ba Sing Se? Could they not have used rogue Earth Benders to break down the Walls faster?
gpt
No, they couldn't, because Ba Sing Se is the most powerful citystate in the earth kingdom. The Fire Nation can get some traitors or captives, but Ba Sing Se has a literal army of the greatest earth benders in the world. In an earth bending contest, they're just going to win with no difficulty.

Using earth benders is going against Ba Sing Se with the thing they're an expert in and you have basically no idea about. It's a fight you're going to lose. Use the drill instead.
