You said not particularly good, while also saying it’s not bad, which puts it between - average. Bloodborne’s combat, average? Nah.
It's above average, just not particularly so.
We can spend our time better than to argue about semantics, but the gist of it is, i don't think it's an element of the game that elevates it above the rest of the landscape, let alone genre.
In other words, if it wasn't for the amazing art direction and world design, it wouldn't be the combat to make it one of the best games around.
On the other hand you take something like Ninja Gaiden, or even Bayonetta, and even with their questionable art direction (i mean, i kind like Bayonetta's, but that's another story) their combat is enough to carry them.
The one really peculiar mechanic in BB is the health regain, in my opinion, though most of the time is not worth it to expose yourself, given the small regain, compared to the massive damage taken.
The parry system with guns (which i find more confusing than a regular parry system tbh).
The weapon trick system is basically a stance system (which again, it's cool, but incredibly simple compared to action games with actual move sets), everything else is Souls, sped-up and simplified.
The one thing i really like compared to Souls, is the nerfed back stab, because i'm playing DkS1, and it's almost impossible to justify the use of anything but.
What set Souls game apart, especially Demon's and Dark 1, was the slow, deliberate animations (that you couldn't cancel out of), the brutal management of stamina, the extensive use of shields (that pushed for an even slower approach) and the limited moveset per weapon, interacting with the claustrophobic level design (i.e.: If you were in a tight sewer, a thrust weapon was preferred to one with swipe attacks, and you couldn't have every type of attack with every weapon) - these things were almost all nerfed (if not outright nullified) in their subsequent games, to turn them into more classic action games, where you use a dodge's i-frames to avoid any attack, but they carried with them that inherent simplicity (or designed shallowness) past Souls games had in terms of raw combat system, with a limited move-set, limited defensive options, but designed in tandem with the many builds you could usually do (though in BB they are restricted and feel more same-y).
Again, i never argued BB is anything less than a great game, and never said its combat is in any way "bad", it's satisfying and looks cool, which is more than you can ask out of most ARPGs, but i just don't think it goes anywhere beyond that.

Also fuck, fuck, fuck playing an "action game" at 30fps with that level of input lag.
Finally, while Sekiro shares some problems with the lack of depth and variety in my opinion, it's such a different beast, that i'm not even gonna address it here. I do think it's got a lot of potential though, i think the posture system is their best combat design idea since Dark 1, and would love to see it worked on, in a sequel.
