With a gate of this size and with the capabilities of this group of people, it really wouldn't be impossible for them to defend the headquarters for another 20 minutes.
Sanguine Warflag said with envy, "If only our headquarters was this good. Even if our opponents were in greater numbers, we would be able to defend it."
Fearless laughed and said, "Everything is with costs and benefits. We have to do this because we are small in numbers. But your guild has so many people, would you be willing to be cooped up in your headquarters?"
To fight with smaller numbers naturally requires the help of terrain and strategies. However, the Sanguine Alliance was a super-big guild. No matter what guild they were against, they would not be in smaller numbers. Thus, such terrains would be of minimal help. After all, while others were unable to enter, they would also be unable to leave.
"Rebirth"'s headquarters design was very rational.
