What do you miss from older games?

So in my last session, my players had a fight with a werewolf. While prepping for the fight and analyzing the stat block, I realized that PF2 has basically finished the slow degradation of mythologically "required" weaknesses.

I have a fond memory of playing AD&D2e in high school where we encountered a werewolf and had absolutely no silver. One of the characters had to run back to town while the rest of us went defensive and just tried to keep it occupied. The character who ran away came back with some silver coins, and we proceeded to use them as improvised silver knuckles to take down the werewolf. Without the silver, we were useless.

Compare that to a PF2 werewolf. Yeah, if you have silver, it's an easier fight, thanks to its weakness. Sure. But there is no *need* for silver. You could kill a werewolf with no issue with regular mundane weapons.

And I fear that loses something. I get the game balance decisions for it to be this way...but I kind of miss the "you better have this or you're screwed" of previous editions. Even the D&D3 style damage reduction worked decently in that regard -- do at least 10 points of damage to do anything unless you're attacking with silver. I know that I could effectively do that by giving them resistance to everything except the desired damage type -- but I run in Foundry, and that's a bit of a pain to set up. Ah well.

Are there similarly (probably unbalanced) things that you look back fondly at from previous editions of the game?
