Remember that Burst damage starts with a 5x rather than a 1x multipler (for SSR kamihime). Therefore any Burst buff's effect should be divided by 5 to approximate the effect on damage. Shingen's ability is a +200% buff, which is why it's so powerful. To get the same effect with weapon skills, you'd need 7 SLVL20 (small effect) weapons, which would yield +42% Burst damage. Meanwhile, 7 equivalent Assault skill weapons would give you +70% character attack, or +31.5% damage. Would you rather have +31.5% damage all the time, or +42% damage on Bursts only?

In short, Shingen is good because her Burst buff (+42% Burst damage) is uncommonly strong vs. the alternatives available for character ATK (e.g., +9% damage from Arthur). Throughout the rest of the game, you don't see that same lopsided ratio.
Man, the damage calculation in this game is really dang complicated. What's the overall formula for burst calculation? Also, if the damage cap increase from the weapon burst buff I see in the JP wiki is actually valid, is that a good reason to run a dual skill weapon having burst buff?
