Remember in her last life she syphons the MCs mana and it's implied she was brainwashing and manipulated people to hate the MC. Also I think her family is stalling until the can find someone to steal mana from while projecting the "she's young and still getting the hang on her abilities" and she's only healing people on the surface not actually solving the problem. And if you think about people that are in pain want relief even if it's brief so they're trying to stay on the healer's good side
I seriously wonder whats so special about Loreina and how the hell they all got so easily fooled in this life like: Loreina has a very special power!/One she cant use? Wow how great; She can heal people!/she can heal one person and not even in one try (not mentioning its not even a healing power at all, its something more like black magic); She's the only healing mage in the empire!/The only one and the only useless one; She will save the empire!/How is she gonna do that when the core of her power are just rumours and she has no real power at all?
Its just frustrating at this point, they all got fooled like damn kids and believed she has any power at all only because there were rumours about it. EVEN EMPEROR BELIEVES SHE CNA ACTUALLY HAVE SOME REAL POWER. That competition to heal him is also dumb. He believes a shitty blond rat thay clearly has hidden motives above the child he claimed to like and trust a lot. Its being dragged as hell and it became boring long time ago since she make almost no progress at all to defeat Loreina
