That’s the point. Pathfinder 2e isn’t different from earlier editions of D&D in that regard. Old-school D&D has a reputation for being very deadly exactly because PCs are fragile and tougher creatures will destroy them. The game evolved the way it did because enough people wanted balanced arena fights, but that doesn’t mean the things you identify as a problem are a problem for a creative agenda that eschews arena fights.
This seems like a shift in the goalposts. So now not only combining encounters but also those with larger scares or varied terrain are problematic too? I think the idea of balance being offered has been distorted in a way that won’t resonate with those who do want balanced fights. I expect those who want balanced encounters assume they should win every fight (without having to engage in war tactics) rather than have them all be so tuned for optimal amounts of exertion from both them and the PCs in every case. 5e doesn’t even do that!
I feel like people talk about "sandboxing" like you should be able to handle problems that are tougher than you'd normally find in a curated experience, and that's totally not the case. It's the reverse: you find stuff that you can't handle, and you should deal with it in a non-combat way like using diplomacy, deception or simply beat feet. In this, PF2 is great for a group that desires mechanical engagement on that front. If you don't want that mechanical engagement, then it's not going to be for you. But it's worth noting that it's not about whether it works or not, but if it jives with your own stylistic sensibilities.
That worked in OD&D because OD&D characters had no skills. It was an empty space where you could plug in whatever approach you wanted. Doing that in a game like PF2 would be really weird because you’d have to set aside various aspects of the characters that should otherwise work in the exploration structure.
Yeah, PF2 is meant to specifically be a unified system. If you don't like that, then fine, but that's personal complaint rather than a systemic one.
