Do the forsaken heal their wounds by simply consuming the flesh of humanoids alone or do they also replace body parts with undamaged/non-rotten versions?
If the latter is true, it begs the question:
At a what point are you a completely different forsaken?
Can you even be the same zombie if, over time, all your original pieces have been replaced?
I would say both. For minor injuries a little food will heal it right up but for major ones, points to metal jaw, replacements are needed. Forsaken are not just their bodies but their minds so as long as the mind is intact we will be the same. Think of ghost and liches.
I had a Forsaken Robo Night Elf in Wildstar that could heal by shooting things.
I could adapt.
My Femsaken would probably choose NE ears if she could.
It’s both and if they didn’t have souls, it would be a ship of Theseus thing but since we know it is just the souls attached to said body, meh.
Magic also heals their body. Holy spells heal the body but it also gives them intense pain. That is why they prefer to heal via shadows, potions or fel.
Like the aspects and Earthens, they’re true immortals to the point that the only thing that will destroy them completely is destroying the whole body completely or them losing their minds.
They’re not demon hunter immortal that they can just regenerate a body in the nether.
Yes because in WoW there are tangible souls.
For example, that’s not Nathanos’s body. That’s his younger cousin’s/nephew’s body, I forget which. It’s still Nathanos though, because his soul was put into that body.
No one really talks about how disturbing that whole deal was.
I have read that 98% of all the atoms in a living human body are replaced over the course of a single year. A dead person, even animated, would probably retain a much larger percentage due to the fact they may not even have a metabolism being animated by magic or ?
I heal by taking a bath.
If you’re just replacing body parts, never.
In Warcraft, souls are real. As long as the soul belongs to the original Forsaken, for all intents and purposes that is the original Forsaken.
You could replace every body bit. You could even remove every body bit. Then you have a ghost lol
Still curious if they could attach robotic pieces to upgrade their decaying body. Probably a question for all races though. 
I have it on good authority that Forsaken also use duct tape to repair injuries.
In reality we replace all the cells of our body within a year, so if you look at your photo of last year ,was it you or someone else ? 
Was that ship of Theseus in a TikTok or something recently? I’ve seen it pop up a lot recently. Too many times to be a coincidence.
This. There’s a scene in Before the Storm when one of the undead characters is sewing on a replacement arm for a warrior.
The Nathanos thing? In that case I think it’s because not many people know because they didn’t read Dark Mirror.
This is exactly what happens to normal souls that go to the Shadowlands. They get shunted off into one of the Covenants and gets a 100% new body, but they’re still them. Baggage and all. Which is why the Kyrians were so big on “forget your past life, just become this all new thing”.
100% matter replacement is 0% relevant to souls in this game.
For a race of undead, pretty weird they’ve never tried to recruit a necromancer or something to weave their flesh back together
Given what it took for Nathanos to have that done, it’s pretty expensive.
Like most high-end cosmetic procedures, really only available to the 1%.
Mostly you’re just noticing now because people like the thought experiment more recently.
They just don’t know it is called the ship of Theseus though.
They replace rotting body parts with cadaver parts. It’s called fleshcrafting. They also sometimes add things like metal jaws.
