Review Detail of xBuu in Naruto : The Wind Calamity

I started rereading this like a week ago and I’m up to the point where he starts attempting to achieve the gate of life, then I had this thought that so far as of the last chapter I read before rereading (chapter 603) he has the 8 Gates Technique (I can’t remember how many gates he achieved before stopping), the Flying Thunder God Technique, Dans Spirit Transformation Technique, and in the future i’m guessing Fujin will get Senjutsu as it’s pretty much guaranteed cause it been mentioned quite a few times throughout the series. My point is, is there a need to give him so many forbidden techniques, I think the Flying Thunder God Technique and in the future Senjutsu are more than enough, and just adding the other two forbidden techniques and maybe more in the future, are just over the top as once he develops his wind domain and is able to infuse nature energy through it and implement Fujin’s vacuum jutsu’s into the domain, those techniques become unneeded. This ain’t really a review, just me expressing my thoughts but this novel is peak nonetheless so thanks for writing such a great novel. ✌️
