Difference between some massive general cleaving multiple men with a giant glaive and some wee lass with some yee yee ass toothpicks is that while both are logically unsound, one is far more stupid than the other.
I personally find the generals's power levels to be tolerable because at least, if they stop moving, they are dead meat, meanwhile, the magic ninjas whose supposed in-universe weakness is rapid exhaustion can apparently fight off entire units on their own
