It's kinda funny because Bloodborne was my first game in the series so because of that I never used a shield in DS3 or what I've played of DS2 so far. It would just feel weird compared to what I'm used to.
Gun parrying in Bloodborne is (from what I've heard from people) easier than parrying in DS so that kinda balances out not being able to block. Definitely feels like a lot of the parry windows in BB are pretty big and easy to see.
I'm just not that into parrying either. I either kinda tank the hit (getting harder since I'm not going a str build, so I don't have 100% block) or roll out of the way. I'll just have to learn and GITGUD
