Now that we've entered the glorious Era of our Lord and Saviour Shingen, why would you not use her?
I might be heavily be using Herc for Tower still just because dat debuff is so damn good for debuff starved Thunder, but next Tower? Why bother when you can just Full Burst like every 6 turns. WITH PF. With absolutely no fast Hime whatsoever needed to help. That fucking skill is so fucking insane.
