Cohorts are sidekicks, not disposable mooks! And the rest guard the castle, not coming on adventures to be slaughtered!
If any of this was ordinary, there wouldn't be armies or castles.
This seems like an exaggeration. Castles are still useful against the Com1 rabble that 90% of the world is, and a standing army of War1's seems like a good idea.
His strategy sounds like a strategy for the PC party, which *isn't* among the 90% of rabble, and often has better access to things like low-level magic.
I think you are quite wrong to think what you suggest is normal. If it was in the remotest bit normal in a campaign world, it would be perfectly normal to a) build all fortresses underground, b) have magical defenses that countered invisibility, illusions, and such on the approaches to the fortress.
You mean "dungeons"? You know, things that PC parties (which have resources like that) face all the time? The core rules suggest that, indeed, these things are quite common. Not as common as castles, but Com1's are vastly more common than adventurers, anyway.
The very fact that there is a castle barbican suggests that spider climb potions are considered rare and wonderful and not ordinary equipment.
Or that they were expecting an army of War1's, and not the elite and powerful Heroes of Destiny that they ended up facing. Elite and Powerful Heroes of Destiny are going to require a bit more than a barbican.
And Elite and Powerful Heroes of Destiny may only be 10% of the population, but most folks are aware of these "adventurer types" because of the power and influence they wield.
It would definitely be an unusual world where a group lead by PC's with access to these powers simply didn't use them.

It varies and there is no standard.
True, but there is a baseline that the rules suggest, which includes a world in which spider climb potions are rare for NPC's, but not for PC's.
