Bloodborne is so much easier than the other souls games if you can get past the sword/board mentality that you developed. Rally mechanic makes it almost unfair.
I don't think it's as easy because bow and arrow completely breaks most enemy AI in every Souls game (hard to believe it is still busted after 4 games) but I do agree it's not really a hard game, other than defiled amygdala and his stupid one shots.
What I actually think makes Bloodborne easy though is how the parry mechanic works, the window for it is absurdly large compared to Souls and in a lot of cases you can actually parry outside of enemy melee range. I was awful at parrying in Souls but in Bloodborne I basically just visceral attacked my way through the entire game (though there are some bosses that can't be parried, but most weren't that hard anyway.) It's even more dumb if you get runes that makes visceral attacks heal you.
