The fuck you talking about? I love DMC3 but in that game you can use healing items by pausing the game.
Ok? The more healing items you buy the more expensive they get. Sure, you can grind for hours to get more, but you can grind in Souls as well. If you're playing both games properly Dark Souls is more lenient about healing. And more to the point it's just generally easier.
