Just curious if anyone uses the health regen enchantments and finds them useful in battle

are they more useful to certain type of characters?

Health potions are far more practical.

It seems to me that your health is easy enough to regain after a fight with the starting healing spell and the regen effect is so minimal during a fight as to be impractical. Maybe if you're trying to avoid raising Restoration for some reason it would be more use?

Now stamina regen....I use that on allot of my characters, but then again I don't use vegetable soup or anything like that when I play
