Questoris Knights seem to only have a single Warlord Trait. I mean, some argument can be made that the Mechanicum specific Warlord Traits can be used, such as The Logic of Victory or the Science of Slaughter, but...they don't seem logical or even remotely useful for Knights. They don't get pinned (your Armigers do, but requires them to be within 6" of your Warlord), and obviously you want your Knight to be shooting or in combat, so the Logic of Victory isn't practical. Also, the Science of Slaughter's +1 to Strength isn't useful to a Knight whose Strength is already 8 or 9.
