Well first off, i'm not taking difficulty advice from you. I'd need assurances from someone on my level, who plays on easy and then still needs to cheese the odd boss.
The other reason I know i'd hate it and stop playing it is that I can't play creepy, dark or spooky games. The whole aesthetic of this, and all the other Souls games, just puts me off.
I'm still really jealous though, because it sounds like the open world design is fantastic, and would absolutely be something i'd enjoy. I'll just live vicariously through others.
