She's not useless alone but she's just one component needed to fully enable your hypercarry DPS.
having a Crit DMG buffer that occasionally heals your teammates is still super useful on it's own.
If you have literally no other specials you can still make do with a poor man's hypercarry by using Kotama (ATK buff) and someone else who can buff ATK or Crit via the sub-skill slot (so there's no overlap where buffs cancel each other out due to competing in the same skill category)
