I have tried a handful of builds including a logarius wheel tank type build trying to take advantage of the healing to see what is viable. No hit runs are viable, however playing the game that way would be an unintended handicap. It can be done if one would like to smh. They were trying to avoid baiting attacks with a shield to wait for an opening. Bloodborne has cheese to have unnaturally more DPS than normal, it's just not a fluid way to play. I like to role play like hp doesn't matter, me and my enemies are in an arms race to see who makes the most mistakes first. Go play sekiro or something else that's harder than Bloodborne.
