Reign merely glanced at the rankings and said nothing. He didn't feel pride or arrogance because he was ranked first, he had just done what needed to be done, what only he could have done amongst his team, and that was it.
Without his Nephilim transformation, he wouldn't have been able to do it, without the power of his race, something he had not learned, earned, or ever thought about, he definitely would be much weaker than he was right now.
That was why he didn't feel any pride, after all, the rankings the others had gotten all came from the hard-earned abilities and skills they had learned and practiced.
That was why he didn't feel that much pride, why he didn't believe himself to be better than others. If he could do the same without using his transformation, as, for example, Radagan could have done, using his mark and ability, that man could have slaughtered the entire horde that attacked them without any issue.
