DLC is totally worth it, though. More difficulties, more missions, 2 new weapons, and the Abyss.
I'll go as far as the combat and ranged options, at least :D I still love me some Bloodborne!
Parry skills make short work of any of the human-sized enemies in this game, and ALL of them can be parried, even (especially) the bosses. They all use the same stances and attacks, outside of Living Weapon specials (FUCK YOU SANADA AND MASAMUNE), and learning those helps you abuse parrying all their shit. If you get good enough, Swords/Dual Swords trivializes human enemies.
Hell, even I can do it, and
I'm pants at parrying (Youtube)!
It is good to know that even as I am in Way of the Nioh, raven tengu still kick my face in. Onyudo? Pffft. Oni? Pfft. Ninja dogs? Pffft (bless you 100% ranged damage reduction). RAVEN MOTHERFUCKING TENGU? Ffffuuuuuuuuu
