There WAS strategy in that war?! What do you think Shikamaru and Shikaku's purpose is in the entire fucking anime?! Strategy.
Hamura weilds tenseigan so I am certain it will be present in "Boruto the series"
Uzumaki justsu's suck anyway. Their bloodline is good for activiating Rinnegan.
If Boruto got Byakugan he would be powerful no matter what you say about the Byakugan.
In Naruto the younger generations will always be stronger. Not always the case but, it's mostly the case. thus, neji's decayed ass is irrelevant.
