Competitive Spirit
Ves cut so many corners that Gloriana would probably faint and collapse if she saw his work.
He did not put quality in mind at all! His only priority was to put as many components back in working condition as possible. In order to accomplish this ambitious goal, Ves relied extensively on his jury-rigging ability to improvise faster but inferior solutions.
An ugly mech was still a mech. Even if its performance had dropped to 30 percent of its peak, it was still a serviceable war machine in most circumstances!
While Ves had to employ plenty of creative solutions to shave off minutes and even hours of his time, he reveled in the challenge.
The pressure of facing biomechs that were able to heal much of their minor damage by themselves constantly loomed behind his back. He knew his opponent would show up with more extensively healed mechs, and that drove him to employ as much haste as possible.
