the difference between blood colors is that big, the things you just said are very good points of evidence. lower bloods are more prone to psychic powers as higher bloods are more prone to physical strength. high bloods also have longer lifespans, trolls of aradia’s blood color only last a number of sweeps (if i remember correctly, the estimate was the equivalent of around 30 years?) while fuchsia bloods could live for thousands of years.

vriska herself said she was a bit of an exception to the psychic rule, though, and feferi may not be the strongest but i’ll be damned if i said that girl isn’t fit. she spends all day swimming and she pulled a full size whale down in the ocean to feed her ferocious monster of a mom, if that’s not a display of physical strength then i don’t know what is.
