The problem with DoH is that it's got very uncharacteristic moves for a Sekiro boss in addition to being gigantic. Many have said that they'd see DoH being a Bloodborne borne, for example, vs being a Sekiro boss.
In my first playthrough, I managed to beat it after many attempts. In subsequent playthroughs, I just didn't wanna bother, so I tried the cheese because nailing that is fun in and of itself.
In later playthroughs, I just don't fight it at all because I don't really enjoy the fight as much. It's cool from a story perspective, the design and vibe is awesome as well, just not that fun to fight.
