The only level I loved in Bloodborne is the Forbidden Woods. And DS3 doesn't even have a zone that comes close to that.
We very clearly want different things out of our Souls levels if you don't think any zone in DS3 is better than Forbidden Woods. It's a good level, but c'mon. There are probably 10+ areas from DS3 I'd put above it. I really don't understand what it is you value in level design.
And better secrets? Dark Souls 1 has entire zones And bosses that are completely hidden. I never found any secret in DS3 that comes close to discovering Ash Lake, the Gwyndolin boss fight, or figuring out how to return to the undead asylum.
Admittedly discovering Ash Lake is a series-defining moment. It's amazing. But at the same time there's very little to do there but gawk at how epic it is. That said Dark Souls III has plenty of hidden zones, bosses, and covenants as well. Archdragon Peak, Untended Graves, and Smouldering Lake/Demon Ruins being the primary ones.
...but a pure spellcaster just isn't viable
? Again, I completed the game near launch as a caster without summoning. I remember it being pretty easy with the exception of Aldrich who is magic resistant. I still beat it after a few tries without compromising the build. Do you mean zero melee allowed? Is that even possible in any of the games? It sounds miserable even if it is.
- weapon arts: have a very, very situational use, cost way too many MP, and require a long windup. So they are mostly irrelevant. Give one or two useful!
There are tons of useful weapon arts. Katana parry/quick attack, halberd/spear charges, long/shortsword shield break, Dragonslayer Greataxe/Swordspear lightning attack, Perseverance, Sunlight Straightsword buff, etc, etc, etc. Honestly looking at the list on the wiki I think most weapons have a useful weapon art. Yeah you need to invest a few points into MP to use them more than a couple times. That's the tradeoff.
Here's the kicker about weapon arts though... they're just extra. Even if you completely removed them from the game you'd still have parity with Dark Souls 1. It's literally just icing on the combat cake.
- revamp the world: it's pretty linear, lacking in connectiveness, colour, and thematically is very...off. Plus there is a distinct lack of useful items in the first third or so. And as a personal note, I dislike how it funnels you into crowds.
Yeah it's linear. Just like Dark Souls 2, the other game you mentioned in your original post. No remaster would change that. It was very clearly a design decision to have you go on a journey to faraway lands instead of having a big interconnected world like Dark Souls 1. I prefer DS1's style as well, but people really need to let it go. It's the only game in the series like it so it's clearly the exception, not the rule.
I'm not sure what you mean about the color and the theme; they both seem great to me. It's a world on the brink of death. It's grey and dead, but there's plenty of beauty to be found as well.
I love the line about funneling you into crowds. Dark Souls 2 is Crowds of Enemies: The Video Game. It really seems like your criticism has some double standards here.
- poise does not fucking work, you see clothed enemies whose attacks aren't stopped by hits. What you said are iframes, poise is broken since release and has never been fixed.
It doesn't seem like you understand how poise works in Dark Souls III. It's similar to Demon's Souls' hyper armor. Poise only takes effect when you're swinging your weapon. It works exactly as it's supposed to.
It was broken at launch though so maybe you just assumed it never got fixed?
- rough edges: most infusions provide close to no benefit, builds lack variety, it abuses hp sponges enemies, how the combat feels is completely out of place within the world (and looks stupid), the weight is gone. The estus progression is fine. The changes in enemy behaviour made shields pretty useless except as an "oh shit" emergency block, because dodgerolling is faster, costs way less stamina and gives you iframes...
Infusions... I've done a refined, raw, heavy, sharp, hollow, blessed, and dark/deep infused build. And crystal for a while early on in my mage build. All worked out great. I know Chaos is very strong as well. That leaves fire, poison, blood, lightning, and simple. I think fire and lightning are probably fine, but poison, blood, and simple are indeed probably pointless. But I could be wrong? Anyway, at the very least it's definitely not "most" infusions that are useless.
Build variety is just as good as any other Souls game except for 2.
The only enemy/boss I'd call a hit sponge is Midir, and combat neither feels out of place nor looks stupid to me, but I guess that's highly subjective. I don't think you'd find many people agree with you. Shields being less sturdy is a good thing. They're way too strong in the other games.
- the engine: textures load very late, playing on ps5 you see texture loading and geometry warping in and out of existence when you move the camera. And even at 1080p, it stutters a lot.
Sounds like a console problem. These issues do not exist on PC.
In conclusion, thinking Dark Souls III needs a remaster is pretty absurd. If any game in the series needs it it's 2.
