AKA: How Medicine is a useless skill in vanilla, especially in hardcoe
Stimpacks. The all-purpose healing agent. What you go to when you're hurtin'. Their effectiveness is governed by the Medicine skill, and can heal up to 90 (or 15HP/Sec * 6 secs for the hardcoe game).
Super-stimpacks. Extra healing, for the cost of some physical weakness. For when the "Oh S$#@" threshold is reached and you need to not be nearly dead NOW.
Doctor's Bags. For when you want to remove that rather unsightly piece of shrapnel from your leg.
So why do they feel absolutely useless in the face of the Survival skill?
Do you know what Science and Medicine does in the real world when some natural curative is discovered? It figures out how and why and what specifically is happening, distills it, and makes it even more potent. What happens in FONV? A freakin' bass-ackwards tribal remedy, the Bitter Drink, outperforms the stimpack! FOOD outperforms it! Even one of the most basic prepared food, the Bloatfly Slider requiring all of 20 survival skill to concoct, outperforms a stimpack in healing, to say nothing of anything higher. And the only ways to deal with poison aren't even in the Medicine category.
At least there's Doctor's Bags... OH WAIT, Hydra outperforms doctors' bags! And it heals over time so you can just down one and not worry about being crippled when fighting someone bomb-happy (looking at you, powder gangers in early game). Once you hit the skill to mix up Hydra yourself, doctors' bags are useless now too, unless you have zero Fixer pills on you and are bound damned and determined not to ever get addicted to Hydra. And once you hit Honest Hearts, you get Daturana, which really heals a lot and doesn't even have an addiction factor!
And then there's perks. How many perks rely on Medicine? Three. How many for Survival? Six, and once DLC is factored in, it goes up to twelve.
And here's the kicker... Apparently Josh Sawyer wanted to cripple Medicine even more than it already is, as evidenced in his "JSawyer" mod by the nerfing of Stimpacks, the insertion of "expired" stimpacks, and the inability to make your own stimpacks (also replaced with an inferior "homemade stimpack"). What happens to food? Some raw foods get their detrimental effects tied to not having Lead Belly, the Sunset Sarsaparilla's absurd healing factor gets nerfed, and... that's it. Even the Bloatfly Slider isn't touched.. Food is an even more potent as a healing agent than a fictional drug specifically intended to accelerate tissue regeneration in the JSawyer.esp module. He even crippled Doctors' Bags so they're even more pointless in the face of Hydra and Daturana. If he really wanted to make it harder to heal, he should have removed the healing effects from *all* the food and left the Stimpacks completely alone.
What can Medicine do that Survival can't do better? Nothing. What can Survival do better than Medicine? Everything. Obsidian had it out bad for Medicine. They should have just sent it out to pasture as BGS did with Mysticism in Skyrim instead of leave it in its pathetic state.
