Tried out Shingen in wind today and was impressed. I used Hercules' Raging Assault for burst rate up, along with the usual team of Amaterasu, Brynhildr, Motu, Dark Amon. My prime concern was being able to get past the first stage without injuries and stun the boss before she overdrived, both of which I did with Hercules Full Break in other attempts.

Shingen being able to burst early in the first stage completely made up for the loss of Full Break damage, and full burst stunned the boss without issue. She also cut off several turns in the second & third stages. Runs today with Apocalypse were faster than previous runs with Belial; I'm sold.
