Berserker technique is bug

Hello
I am a berserker player and I use the “berserker class technique” engraving. As I’ve been testing different etching options and gear combinations, I’ve noticed that the berserker class etching is not causing the increase in critical damage that it should.
In addition to the fact that visually there is no change in the critical damage stat when I activate the burst mode, there is also no increase in the damage done by the character (I was testing it in the training area in trixion) so this for sure goes further beyond a visual bug and represents a great detriment for those of us who use this engraving.
I appreciate any answer you could give me and I am attentive to give more information that you could request.
Greetings.

What a comedian hahaha
