i covered howl. I can take way more hits as a human and im light armored. i can also take being nuked as a wolf i get nuked i instantly die.
As a human you're armored, likely enchanted, and likely have some nice perks for wearing full armor sets. As a werewolf, you're completely naked, so any health-boosting or protection enchantments will be gone. You may have some protection against normal weapons, but not magic or silver/daedric/enchanted weapons (which you may be extra-weak to), and you may be weak to fire, too... it's difficult to tell exactly what your protections/vulnerabilities are without the CK, but that's the basics of how it usually works. Beast form gives a slight health boost, but not much to counter being completely unarmored if you're not leveling health (so master difficulty and high-level enemies will be extremely dangerous).
Again, yes, there could very well be ways to re-balance it so you don't need to spec into health like a warrior to play as a werewolf at high levels in high difficulty, but it would need to be done carefully. As mentioned, my mid-level (about 25) mage (who only upped health once, never upped stamina, and has no one-handed skill to speak of) has no trouble taking out normal enemies. If you buff werewolves too much, you'll turn them into walking gods at lower levels or lower difficulties.
i am level 30 on novice difficulty and silver hand guys with 2h silver swords kill me
Werewolves are weak to silver, and 2H weapons are naturally deadly. How much health do you have?
