First, its more like Veret vs Spharai. Veret is better for dmg Spharai is better for defense. Masamune is better for dmg and Kogarasumaru is better for defense. I'm not sure if anyone done some testing on :rana lately? With so many DA+TA stacking (aftermath from mythics works for WS from what I remember) multihit WS can be pretty good.
Looks kinda lazy(The weapon, i mean) ... its like, Literally 1 boost. its a Average Damage GK (with low Delay meaning a lot more store-TP needed for 5/6-hit, SE seems to not notice low delay isn't always better).
I know I'm no SAM but i think even the TP Bonus+100 Magian weapon is better than this...?
But i'm getting ahead of myself, Most people will take this as me bashing him for his choice, when infact its just a analysis of the weapon :| not of the player.
