I was actually unaware that the powers of the Namikaze clan were subjective to full heritage, so that is admittedly new to me for sure.

Minato being nerfed in the war was certainly necessary, and I did already feel that way when I first watched Shipudden. I do still have hope though, that Kishimoto will one day expand upon the lineage, and offer some sort of advancement for the Uzumaki's through untold stories of Minato.

I understand why many would prefer to see them grow powers through their own efforts too though (like Rock Lee simply pushing himself hard enough to become great) and I would love that path just as much.

I know a lot of people got exhausted from the huge role that heritage played in Shipudden (understandably), but I also feel like those are still among the most interesting reveals throughout all of Naruto :)
