Apparently the dmg one beats out the hagun on Rana, but the Hagun just edges them out on Y/G/K
In short that yeah, It's badass for rana i have the raddenotachi myself. Hagun will slightly win for y/k/g still but i can't wait to see the next path or so.
Realistically, it depends on how JA/WS delay is quantified.
Hagun, Soboro, and the higher damage occasionally attacks twice GK are all within less than 5% damage of each other before quantifying it, though clearly Soboro and the OAT GK are losing more from WS delay than Hagun is.
