I see I am late to the party, but regardless welcome back
@Velorien ! As a homecoming gift, allow me to offer my two cents to this discussion.
This is only
mostly true; not
strictly true... unless you are being very generous with your terms so that 'power levels' includes a simulated person's natural intelligence and 'resource access' encompasses his education as well. Just because Grog the caveman and I have roughly the same physical strength and we both live in some resource rich woods does not mean that Grog will figure out how to create metal tools as quickly as I would given the same amount of time.
But let's be generous and say Grog is an exemplary young caveman with a keen intellect. I agree that if he and I were to stumble upon two steel axes he would probably be able to figure out how to use it just as effectively as I could. He and I would both be able to chop down as many trees to our hearts' content. However, the difference I am trying to distinguish here, is what happens afterwards.
Grog will have plenty of wood to use for his caveman needs and he may even use it for other purposes besides arboricide. However I can examine the axe and from there use it to learn about where it came from and how to make other crude, but still metal, tools in time. I have knowledge that Grog simply doesn't possess and the wherewithal to implement it, just as Hazou has us to give him novel ideas to use in game to give him a huge competitive edge.
So long as we are relying solely on the techniques given to us by NPC's, I agree that they will not give us an overwhelming advantage. That said, knowledge is power and simply having more military spells than your opponent can be the deciding advantage if all else is equal.
I do disagree with this though. We were able to create Skywalkers by taking something everyone else already had written off and adapting it to a new use. It's the difference between telling two people to be creative and then handing each of them a pencil and a piece of paper followed by isolating them from all outside interference, including each other. One might walk out with a deeply moving, yet inventive short story whereas the other might take his piece of paper, fold it into a paper crane, use his pencil to shade it in an unexpected fashion, rip the edges of the paper so that the wings look like they have real feathers, and then use the pencil itself to color the beak and feet after splitting it into workable pieces.
This isn't even going into how the hypothetical proctor never said they had to use the pencil and paper in the first place.
My point is that being not just creative, but
truly original is excruciatingly hard. It is much easier to simply follow others' examples and use the same methods that they do to achieve satisfactory results. Real, revolutionary innovation takes daring to spit in the face of conventional wisdom.
Hazou can cheat since he has access to all of our collective brain power and even more indirectly our world's history. Not only are we a Yankee in Kind Arthur's court, we are a Yankee battle wizard with indirect access to the internet in King Arthur's Court. If it weren't for all of the events in the story demanding our attention I would be disappointed in ourselves for not having conquered the Elemental Nations and the rest of the world by now.
Such a world is lethal, sure, but it's still centuries behind ours in terms of technology and other academic advances. All we need is a bit of time to steer Hazou in the right directions so that he can begin unraveling not only the mysteries of chakra, but also rediscovering all of the natural sciences you and I take for granted everyday. It should take him considerably less time too since we already know what to look for and how our normal reality mostly works. Reading as many books about natural philosophy is a good start, so the next step now, if we can find the time, would be to test Hazou on how well he can function as a scientist.
I don't want world changing power handed to us on a silver platter; that's Naruto's shtick. I want Hazou to build a better world through many small yet interconnected inventions that add up to be worth far more than the sum of their parts, like Zeppelins.
