You know what makes Aymeric and Haurchefant special?
Despite having every reason to be cold, vengeful, mean and selfish people-being bastards, living in a house they weren't born to, growing up in an environment as hostile as Ishgard, having inherent beliefs different to everyone around them- they still chose to be kind.
I think it takes something away from them if we assume they were simply born with a kinder deposition.
Haurchefant was bullied by all of Ishgard, including his step mother, for being a Greystone. Aymeric was adopted and has really low self esteem because he probably grew up hearing how ill deserving he is of everything he got by being adopted into house Borel. Yet they both made a conscious choice to be better. They wanted to treat others the way they wanted to be treated themselves. They wanted to love and invite change when Ishgard taught hate and stagnation.
This is why the warrior of light would've failed in doing everything they did if it wasn't for Haurchefant and Aymeric. How many warriors of light have tried helping Ishgard before us? Over hundreds of years of war, this revolution can't have been the only one. Yet it was during our lifetime that the stars aligned perfectly to have Haurchefant aid us and Aymeric lead us into changing Ishgard for the better and bring about peace.
Without Haurchefant, we'd have ended up in prison and possibly executed (he saves us again by taking a blow meant for us) and we wouldn't have been let into Ishgard. And without Aymeric's trust over his best friend he wouldn't have let us go to Dravania and afterwards, invite the reality shattering truth about his ancestors' actions and usher Ishgard to peace and unity.
Everyone hails the Warrior of Light as the antithesis to bad with absolute power. That, if they're there, everything is solved. But without Haurchefants and Aymerics, the Warrior of Light would be nothing and would not be able to solve half the problems they have solved.
