You cannot be serious, Pyromancy flame doesnt require anything you dont need to build for it anything, just be pyromancer through your build to deal damage with it, all you need to do is actually upgrade it with the materials, what this means is it allows you to be pure pyromancer. You build a pyromancer and you can use the flame, you can also ditch it and use demon scar, you can just infuse weapons and use them instead.
Have you played PVP? You can technically wield some special weapons if you have quality build but its going to be badly optimized, for some special weapons like those in BB, they require multiple stats, you need to invest in them accordingly to get your scaling right and to get the most out of them, this is a build catered for weapon. When you make a build not catered for a weapon you basically build the character for a playstyle instead.
Mage -> Sorcery -> INT 50 -> use all spells -> enough output to sustain the build.
Sure you can mix and do better builds but this one is viable and fun throughtout the game, because it allows you to deal every situation, you will have magical weapon attacks, spells and cc.
Pyromancer -> Dark magic and Fire -> Faith 40, INT 40 -> Use spells or special weapons -> tons of tools and versatility to play your run.
In Souls you dont need to go out of your way and put stats to play, you do your build and adjust the weapons and the tools accordingly, if i want a melee as a wizard i can infuse my lothric sword to crystal lothric longsword, i have a buffed staff and i can use all sort of magic and attacks at my disposal.
The scaling on Trick weapons will sometimes force you to put stats here and there, lets say you want to do an Arcane build, your only weapon available is Kos Parasite (thanks dlc), so if you want to play this build you are stuck with one weapon and few spells for all your run, if you want to use another weapon, you need to rebuild the character entirely.
In Bloodborne, if you make a bloodtinge build, no strength or dex or arcane, how do you play?
Pick a gun -> Lock into enemy -> shoot.
Actually lets stop for a bit, tell me what builds/classes can you do in bloodborne? and how do you play them? How many roleplaying options you have?
In Souls you can be: Pyromancer/Dark, Faith, Sorcery, Quality, Strength, Dex and Luck (poison and status effects - its low tier but its still a build)
In Elden Ring you can do: Bleed builds, Pyromancer builds, Sorcerer builds, Strength Builds, Paladin/Faith builds, Assassin builds, actually why do i need to type them all, have a look:

In Bloodborne you can: Quality, Strength, Skill, you technically can do Bloodtinge or Arcane but they SUCK in comparison to the alternative builds in Souls, they are half baked and feel unfinished, their potential is not realized. Ofcourse now the fans will disagree with me on this, but when Bloodborne 2 comes out and improves upon this they will suddenly notice it.
Lets take a look at Bloodborne builds

Notice how most weapons overlap, there is no real variety here, all builds you will do lead to the same way, with very very few exception (kos), thats because most weapons in the game require multiple stats, and their scaling goes for multiple stats, this way your build isn't a build anymore, not a playstyle, but rather allocation to maximize damage based on the weapon you use, this exactly matches the example i gave with the crucifix of the mad king and how it makes you do compromises just to get the most out of it, so it essentially fuck up your build and forces you to specialize in it.
Also builds being strong is not really an opinion lol, did you play PVP during ER release, there was certain builds that overpowered others, frenzy, bleed, magic, etc.etc.. comet azure is good against some bosses but its dogshit against others, you have multiple spells and ways to deal with bosses, powerstance or bleed, i used halberd spear with ice attacks and fire cancels, it was a burst build and worked wonders for me, there is nothing resembling that in BB, you have to be kidding yourself to even attempt to make this point.
