Comments of chapter undefined of Naruto: Ultimate Rock Lee

Dude, giving him immortality would just suck the fun out of writing the novel. Oh, someone way stronger than him just attacked him? It doesn't matter because he can heal from any damage and will eventually just outlast the person he's up against. See? See how boring that would be? Besides, infinite vitality would give him infinite Chakra and that'd make his Chakra Control absolutely horrendous. With his current gifts, he'll be able to easily use the Eight Gates Technique once he's trained enough. Much more so than the original Rock Lee or even Might Guy. His body is incredibly sturdy and full of life-force/vitality after the first gift he gained. And with his enhanced heart, he'd actually have a pretty decent chance of surviving the Eighth Gate without just straight up dying or becoming crippled. He'd be exhausted and injured, sure, but that's better than the alternative, right?
