Treyton's method naturally consumed more of his own strength, making him slower in setting up the covers. That was also why Luciel had stepped in to help, even though he had seen Treyton handling it on his own.
If Treyton really had to set up all the protective covers around the base walls by himself, his combat effectiveness would surely plummet.
It was better for Treyton to stay active in battle, as his offensive abilities and lethality were extremely high.
It's better for Luciel to have more people like Treyton who could kill a lot of birds so that Luciel could also rest earlier.
However, Luciel knew that he probably wouldn't get the chance to rest. He could clearly see how desperate the others were as they tried to stop the birds and drive them away from the base.
Treyton and the others were obviously already exhausted from fighting the first batch of birds.
