"I tested what the entire war would be like when this monster army arrived at the city gates… It will be really hard to control…"
William didn't delve this deep inside the monster army to try and take them down. He wasn't this delusional to commit such a mistake. He just came here to test how hard it'd be when things would be heated up.

They were using tactics in the middle of their attack. If one didn't look closer, he'd not notice such subtle moves and changes in formations these monsters used.
