Possible error after July 2019 patch (Ninjutsu damage)

[Zhronne]

Hi, the Mochizuki Hatsuburi head equipment (all versions) had an augment that gave up to 25% Ninjutsu Damage to "san" ninjutsu spells.
After the latest patch that augment is completely gone and the equipment received a new one affecting Innin and Yonin.

This seriously hinders NIN's damage potential and it's actually a nerf rather than a buff. Despite having access to all 6 spells at the same time, their maximum damage potential is much lower than it was before the patch (25% lower).


I wonder if this is meant to be or just an unwanted mistake? Something similar happened with the WHM patch, they forgot to add the Relic bonus from Legs/Feet to Protect and Shell, but that was corrected one month later.

Can we get an official response from SquareEnix concerning this issue? Thank you!
