that is what approximation is. it doesn't mean equal. can be better or worse. it has enough similar traits to be viewed as kogetsu/scorpion version of scorpion/kogetsu attack. I totaly agree that throwing scorpion is nowhere  near as good as senku but it's scorpion's way to increase its range (to kill an opponent out of blade range; even though senku is a blade, but as I said approximation).

you don't need a shield during mantis attack - it's a blitz attack, to surprise the enemy and if you cannot perform it quickly it's loses its value. it's not something that should be repeatedly used behind the shield.

you talk about base and give kogetsu an optional trigger (senku) but but subtract one from scorpion (grasshopper). If I remeber correctly scorpion doesn't need an optional trigger for any of its techniques. So compare now scorpion against plain kogetsu. of course you can consider base as a plain trigger or as a combination of triggers to work optimally. in the latter case kogetsu needs senku and scorpion needs optional trigger for maneuverability.
