You mentioned that we're all set up to be at peak physical performance. Does that solve things like chronic illnesses or bad eyesight as well? And for 3/4ths of the Heroes, do they start off with a portion of their capabilities being beyond peak human? Might/Finesse, as an example, having flat out superhuman strength and reflexes? Or is that all based off of their potential for growth in those areas?
It would, I imagine. Though we didn’t have near-sighted (or far-sighted) character in the last versions to my memory. The magic the wish granted your characters has imbued them with essentially the “magically peak human” attribute. As for capabilities the only one with a distinct disadvantage is the spellcaster, but that will gradually be leveled out. The three other heroes will have subconscious instincts programmed into their brains, so for instance despite never learning how to use a bow and arrow Polaris’ character has the instincts and aptitude of an expert ranger. With Defense and Might this quantifies to their strength.
They will still need to see and learn specific techniques, so at the beginning they will be the equivalent of an untrained prodigy. In the last RP, the five-foot-nothing Hero of Might picked up a thick tree branch and swung it at a goblin, crushing its torso immediately by the impact. I think that should answer your question somewhat in this regard.
