So I just had an idea for a feature I'd like to have incorporated into the game. As you might expect, I have Bloodborne on the mind.
Be "Re-Borne"
Upon starting New Game+, transfer all of your stats and items/equipment to a newly created character. Feel free to change their appearance and even their gender, and re-allocate your currently obtained stats to whichever type you want! Tried a STR-based build in your initial play-through? After being Re-Borne, re-allocate those previous STR points into SKL and try out some new weapons!
*Note*
This can only be used upon the completion of the game [New Game+ included]. To re-allocate them again, you'll need to play through and complete the game again.
I'm not sure if this would be something From Software would incorporate or not. I'd love to have it, though, since it would be akin to "inheriting" your previous character into something new. You could, of course, start over fresh from scratch if you want.
