Well, I’ve noticed a trend where some of the Overwatch heroes have skins for closely related or opposite concepts of what they actually are: Imp/Devil Mercy, Young Ana, Mechanic/Engineer Brigitte, etc.
Why not make a skin for Mercy that’s a nurse outfit? White form-fitting nurse uniform, white nurse cap with the red cross on it and wings of white energy. Nurse is related to doctor!
That, and let’s face it, Blizzard, you want to make money off them skins, and who could resist Mercy in a white nurse’s uniform with a nurse cap?
It’ll sell better than Pink Mercy did, and I think almost anyone will admit as much.
I think that was kinda the idea behind her combat medic skin - but that was just an adjusted battle nurse. She had her doctor skin in the comics and I’m sure that one will be added at some point too
Like I said, though, you’ve got stuff like Mechanic/Engineer Brigitte.
The distinction between engineer and mechanic is largely the same as doctor and nurse. Engineering requires much more education, etc., than mechanic, but it’s the same category of profession.
