Ok, I Understand A Healing Quirk Like Recovery Girls Is INCREDIBLY RARE. But Think About It, Wouldn't

Ok, I understand a healing Quirk like Recovery Girls is INCREDIBLY RARE. But think about it, wouldn't other little healing quirks not be so rare? Things like "form a scab at double the speed" kind of thing. Or, heal a wound in half the time: instead of taking a bone months to heal, it heals in half that time. It's not super over powered in my eyes to have something like that, but if you think so let me know, I read it in a really good fanfic once.

But also: What about people who's quirks can be fairly powerful, but aren't really combat quirks. Take Eraserhead for example, his Erasure quirk is crazy good, but all the combat he puts in is hand to hand. I don't understand why we don't have more hand to hand combat with medics who don't necessarily have healing quirks? They have modern medicine and their six years of schooling. (I've looking into a lot of this and 6 years is the minimum for your medical degree in Japan.) They can provide a ton of battle field support.

Idk, it all kind ties into my own story I'm writing and so I wanted to get more opinions and, if you have cool ideas for quirks that could be helpful like for my example: my character has a quirk where they emit a pheromone that reflects their emotions, and use it to flood an individuals conscious. So all they can do is stand there and breathe. That's at 100% which they only resece in combat. In regular use for their work, they use it to soothe the feelings of their patients so it's easier to treat them, and for the ones who pass, they pass knowing they were loved. However, even at maximum output, his quirk offers no healing effects.

But all their medical training and knowledge is from passion and 10 hard years of studying medical works.

So, yeah, lmk what you all think, and if you have cool ideas for non medical quirks that could be beneficial in a medical setting and I'll be sure to credit you on my AO3, whenever this goes up.
