Ignoring that its not about physics but weapon category and design choice (and that broken war is you sticking a metal-sentient shard with only bits of energy into people vs bludgeoning people with energy waves), greatswords due to metallurgy and resources were better cutting weapons than katanas when period compared and. Higher base damage and heavy attk damage. War has stats higher that Broken War too remember. It can still slice through things but not as much as bludgeon them. Greatswords were designed to knock people of horses and for blunt force damage. Katana will slice through things as its lighter and sharper, built for close quarters combat. Its like comparing a Katana to a Greatsword in real life. War is bigger and thus heavier than Broken War. I'm guessing 'Shard of War' is some weirdly translated version of the sword Broken War? In fact, transfer the critical chance from the shard of war to the war, and change the impact damage in the war - to the advantage of the slash damage.

So the same with crit, why the chance of a critical hit for a shard of war is higher if it is part of a HALF war. Although the shard of war is a PART of the war, and in fact, with the second part - the war should have the status of slash the advantage of the part of logic. When there is a war, it has mostly impact damage. I wonder why shard of war (in fact has predominantly slash status).
