It’s hard because I do like what Blood Vials help to add to the game, and generally what they were going for. I don’t think just copying and pasting the Estus system exactly would have worked for Bloodborne’s combat pace, I think having more fast to use but individually weaker healing items suites it well. They just kinda fumbled the availability, they went with something more like Lifegems from DS2 but without the nerfed Estus that helps to make them relevant.
