She doesn't bring anything unique to the team....Until now you could have said hey she is the medic but now naruto can heal someone by just touching them......he is more efficient ands better in everyway....
Sakura might be better in mass healing (multiple ppl at once) and prevention healing (with Byakugo, being able to take hits and have it healed without seals or having to touch anywhere with her hands), but yeah, Naruto has become pretty good at healing.
Having 2 medics in your team increases your healing power though.
It gives more flexibility if someone is wounded that more than 1 can heal.
Sakura could use something extra now though.
A good genjutsu.
Sage abilities.
Kimimaro like bone ability.
Obito's sharingan.
Mokuton like Hashirama (and with that chakra absorption).
(seeing the icon on his forehead in sage mode looks like the Haruno symbol).
A good ranged jutsu.
Something from a list like this.
