Personally, I've never understood the "I want combat to be like Bushido Blade / Counter Strike, where I'm a 1-Hit-Point-Wonder who can die instantly from any random sword slash / mace hit / bullet" point of view.
Sure, in a non-campaign game where you respawn constantly and a full "game" is over in 10 minutes (like Counter Strike), but why would anyone want this in a game where you're supposed to be a Hero? wading through 50+ hours of enemies?
... Apparently you've never played Counterstrike. Unless you're using specific weapons, the average kill shot is more like 3-4 bullets, and up to 11 for SMGs.
Still, it's not about the length of game that really determines it, but the atmosphere. If you've got impactful, visceral combat where each blow feels heavy and painful, you don't want the person to soak up damage all day and degenerate the game into retreating and then getting in as many hits as you can.
With health being more scarce, you have to be very keen to not make mistakes. You have alchemy/potions/healing spells to assist you if things start getting hairy, but if you go into combat blindly expecting to just mash attacks and idly block, then you get severely punished. It's all about immersion, and keeping the combat engaging and fresh every time.
