To this i wanna throw out that hollows vary in strength and you make a hollow that your char struggles against and becomes better because of it. Character development doesn't have to depend on other people.

If I were controlling the mission then sure, I'd make a Hollow that I'd struggle against. But I doubt anyone would have troubles with a few shitty normal ones. And it depends on the character.
