It's weak in the term that It only give you enhanced eyesight. And kinda useless for someone that won't be using taijutsu but a katana.
Did he? But i also meant in general. Gentle fist stance don't really use kicks that's what i meant like "taijutsu like everyone else"
It does more than give enhanced eyesight.
Not to mention using kenjutsu it would be beneficial to have extended range and be capebale of seeing neigh 360 degrees field of view.
Byakugan can also follow high speed movement, not on the level of sharingan but it can nevertheless. it can identify chakra by the specific individuals it originates from, determine when genjutsu is being used, and discern certain types of clones from the real person. Its ability to see chakra is acute enough to see the chakra pathway system and the 361 tenketsu that run along it.
The utility of having one of the 3 dojutsu regardless of which one is still incredibly useful.
Byakugan alone would make him excellent in tracking and intelligence gathering. I'm not sure if all you're thinking about is combat which even byakugan is still a benefit when compared to not having it. But then again, Naruto has never been about anything other than fights.
There was like one series of chapters that actually highlighted what tracking people can do. (Kiba, Hinata, Shino, Karin). So I can understand why you'd see it as weak.
