Skyrim diseases are nothing.
Another case of Beth being too scared to make a daring move against the player.
In Daggerfall, an untreated disease would kill you. If you were too far from a town to heal, then you're sorry ass was starting a new character.
Lol, i was just about to say that. Like 10 years ago, i remember catching Witches Pox on one of my char's when he was far from town and didn't have a Potion of Purification or any Cure Disease spells, whenever i'd attempt to fast travel to the nearest city with a Temple, i'd arrive dead. I also fought a Vampire for awhile to catch Vamprism, and when i did, i also caught the Bubonic Plague (Black Death), and i'd die before i could turn into a Vampire. Pissed me off, because i had to cure it along with Vampirism, which Vampires only had a 0.6% chance of infecting you with Vampirism, so you had to let them beat on you for awhile, which also more often than not, got you diseased with something nasty. Vampires, Mummies and Zombies carried the nastiest sort of diseases, crap that would drop you dead within a few days.
Interesting thing about Rockjoint, is that if there's a magic effect that can decrease the amount of damage you do with weapons, then there is also a way to make a magic effect that increases the damage you do with all weapons. Add that effect to Vampirism to make it stronger. Preferably as part of a new "Volkihar Vampiris" strain, a Warrior-like strain while the "Sanguinare Vampiris" strain is suited more towards Assassins.
