My dude, if you spam the crouch button while at 100 stealth you can stand on the face of people and they won't see you. You legit can hit them with a dagger for x30 dmg (off handing a mace for stupid dmg) and they don't recognize your existence. Oh, you do onehsot them with that tho. But still.

100 stealth completely breaks the game.

Higher difficulties made me do stealth archer more. Needs multiple hits to take down this now very dangerous enemy? I'm not doing that in melee, or with some limited resources like a mage. I'm flinging pointy sticks from inside the walls.
