DS3 is the only one with proper enemies, level design and combat.
The best enemies in the game are pretty much reiterations from the old games but worse because of the new combat's nature.
And the new enemies are cheap because they have pretty lengthy combos and seem to have infinite stamina. Then enemy mobs seems to have been placed without much though to them, and it's disgusting how most of them are harder than a lot of the bosses.
Level design has always been good (and DS2 has by far the best levels in this regard).
Also this point is the hardest to explain, because it's also the most subjective: while most levels are well designed, they just don't feel as charming as they were in DeS and DS 1/2; they seem to have been developed in the most boring way possible; like... they thought of a cathedral and then increased it to the third power - the first area for example, just seems like a city on top another city; it's big but empty, and when everything is that big and amazing, it loses impact halfway trough.
And again the exploration is very mediocre in this game.
As for combat.
The enemy speed, life and damage has been increased to ridicolous levels. Plus most enemies and bosses feel the same when figthing.
Poise has been removed. In fact all the stats went from being well done and polished in DS2, back to the broken mess of 1 (if not worse).
Dual Wielding and power stance was removed for reasons.
OP spells.
Parry and backstab again became cheap ass shit.
Also 5 damn games later and they still don't fix collision.
DS3 has a lot of cool items that can buff weapons & add attributes. ... And abundance of items also means that you actually use your consumables.
So did the other games.
you say, they changed combat to please Bloodborne fans, but that is not correct.
Again there's no poise, enemies have overly lengthy combos, infinite stamina and most bosses, and even enemies, play like Artorias/Orphan of Kos (i.e. spam those roll and ligth attack buttons).
Demon Souls combat is much faster than Dark Souls 1/2, all they did was fix the sluggish combat from 1.
DeS still has a far slower pace to the combat compared to DS3. Also you are talking like the combat being slower pace is a bad thing.
Parry timings were widened in DS3 as well, & parry tells are much easier to read. I used the gloves to get insta parry & worked well with bosses.
Insta parrying enemies bigger and stronger than your PC as always been dumb and exceptionally chep.
Also, everything was fair. It was designed like a game and not a fckn murder trap like SAW. You can tell things & caution actually paid off.
That's something they already since DS1, and I would even argue since King's Field 4 (from 2001).
I do agree on the exploration as DS3 is undeniably linear & corridor like. But I prefer well balanced combat encounters and great bosses, and DS3 delivers best there.
But the thing is, the Soul games focus, it's main draw as always been the exploration of the levels and the world. They are spiritual sucessors to King's Field. They are Dungeon Crawlers, not pure Hack 'n' Slash games.
As for Bloodborne, it is 3rd last, above Sekiro & DS2.
DS2 and DeS are the best game From has made in the last 10 years.
