Does anyone think that Fuurin works better as an ordinary human drawn into the Healin Good PreCure's battles rather than a wind spirit given human form?

Seriously, we could have an adult main character Cure before Cure Butterfly in Fuurin/Cure Earth if the writers did'nt chicken out. Plus, she could had actually worked as a virologist that was drawn into the battles between the Healin Good PreCures and their Byogen foes.

Thematically wise, it also plays into the fact that epidemics can draw in and affect ordinary people.
