I agree that Sarada should learn medical ninjutsu. Even if she is predominantly a combat type she can still use medical ninjutsu for offense. This has a ton of untapped potential for her character to leave her mark and not just be a Sasuke or Sakura clone. Im hoping for a medic sage mode from shikkotsu forest!
I think Boruto should medics, it'll go good with his Jogan and GF style instead of make a full blown clone that way he'll have a way to heal. Sarada can learn Slug sage mode and heal that way and Mitsuki can already heal. Everybody wins.
