dude u speak as if Boruto trained for 10 years...he's still weak as a young shinobi
1. Boruto is said to be a prodigy to learn techniques at rapid speeds
2. Boruto having many variants in his Justus and inventing two of the techniques.
3. Made Hanabi go serious ENOUGH to Boruto due to his agility and versatility.
4. Threw a gigantic Rasengan at momoshiki (surprised he could even hold that thing).
5. Palmed the crap out of fat Kagemasa which caused him to fly at rapid speeds causing some destruction.
6. Having 3 elements that being wind, lightning, and water.
7. His speeds and fighting style proves to be crucial when fighting against the Nue.
8. Has battle smarts, probably will be on Batmans’s level when older.
9. Actually utalizes his shadow clones unlike Naruto who spammed the damn thing back then, so it’s best if Boruto deals with minimum shadow clones.
10. Gains the power of the seal and the eye i which in the future he will utalize them and fully manipulate his powers, combined that with what I said above.
Conclusion: I’m pretty sure through all the 12 years he went through, he doesn’t look like a weak Shinōbi to me fam.
