It wasn't entirely unreasonable for Rhode to make such a decision. Even though the other party might have a certain advantage in terrain, he was still better than them. Because not only was he really familiar with the buildings, he was also clear about what purpose they served. This was something that the other team was absolutely inferior to, so he was confident enough to shake them off and teach them a lesson that they would never forget. After all, it wasn't a matter of reciprocity and he couldn't always be the one suffering, right?
And as a matter of fact, Rhode was really about to teach them a lesson.
