I think this is just gameplay balance. The former was also in TF2, and the latter is so she actually has to reload. Widowmaker firing 30 scoped shots that don’t need to charge would be silly. Not everything in game needs a lore explanation. Just look at Roadhog or Sombra.
Well, in my language - Polish - they’re called karabin maszynowy (machine carbine) and karabin snajperski (sniper carbine). So it’s 2 carbines in 1 and it makes sense with Widow’s Kiss.
He can survive taking an arrow to the head, then heal back the wound from huffing a can of Hogdrogen (which is not universal healing. Its a compound that counteracts the effects of radiation). His hook can also pull D.Va’s heavy mech just as easily as it can the pilot inside, and it is capable of being hacked by Sombra.

mercy self healing (that fast, anyway)

Widowmaker existing at all,
lots of things just make more sense if you dont try and find a reason behind it.
Amélie returned to Talon, and they completed the process of turning her into a living weapon. She was given extensive training in the covert arts, and then her physiology was altered, drastically slowing her heart, which turned her skin cold and blue and numbed her ability to experience human emotion.
Hard light technology is exactly what it sounds like. It makes light into hard, physical technology. This one is also explained as much as it every will be.
The bigger debated mysteries are things like Zen’s healing (you mentioned), Shimada Dragons, and now that we have it, Immortality Field.
She would be dead, only logic behind it now is “lol science” which is really akin to a fantasy setting going “lol magic”
say she can live, second she goes somewhere like Junkertown where it’s abnormally hot (40 degrees celcius or more)
She would definitely overheat.
and thats using an extreme, anything not suited for her abnormally cold body is a death sentence to her.
Why does it matter if it’s biologically impossible by real-world standards? Overwatch isn’t the real-world - it’s a science-fiction future Earth. If they say it works, then it works.
