Aye. It seems that the Norn have realised that other races do band together under leaders rather than doing all their fighting as individual heroes as the Norn do. However, while they don't necessarily expect every member of a different race to be a hero, they do expect it of the leaders - and they expect those leaders to be making the decisions themselves.
In the Charr, this is self-evident. While the Charr do care about bloodlines, a descendant of the Khan-Ur still needs to prove themselves before gaining any respect among the Charr - however, one that does becomes the sole leader of their unit. Thus the Charr leaders fulfill the requirements to be a 'hero' through the eyes of the Norn.
Humans, however, have the quaint little customs of choosing their leadership purely by bloodline regardless of the suitability of the candidate. Now, while we don't know yet whether the Krytan queen is really as weak as the Norn think or whether it's just that other quaint little human custom of consulting with one's subordinates rather than acting decisively on one's own as the Norn expect, when the Norn look at the Krytan queen, they do not see a hero.
