the games do a poor job of making the HP stat attractive to level and a lot of the assumed difficulty comes from players taking one to two hits from bosses and dying and grinding until they rng through it, and thinking that's the intended experience.
in ds1, 30 vit is normal mode, and 50 is easy mode.
if i were to try and make an easy mode to dark souls 1 that i think didn't take away from it, it would just be that you get more souls per kill. idea being it just nudges the player into the systems a little harder instead of having them disengage.
