Actually I kind of see what you mean with having to have towers to pop every Armored layer, but if you think about it, Lead Bloons have kind of become the joke Camo Bloons had been in BTD4. Here is all the towers that have upgrades to pop Leads or can pop them by default: Dart Monkey, Tack Shooter, Sniper Monkey, Boomerang Thrower, Ninja Monkey, Bomb Tower, Ice Tower, Glue Gunner, Monkey Buccaneer, Monkey Ace, Super Monkey, Monkey Apprentice, Mortar Tower, Dartling Gun, Spike Factory, even Monkey Village, which also has an upgrade that lets every tower in its range pop them. Every Tower that can attack has some method of popping Lead Bloons. It's just balancing.
