I wanted to address this in a bit more detail. Mostly that when designing an RPG you control the setting as well. I would say design the setting but sometimes you just choose it which is enough control for this point. Which is that I assume that most people are working on an system for a setting they want to mimic. Or even more extremely, are developing the setting with the system.
In these cases it shouldn't be a problem. Or not inherently, good design and good world-building can be hard and so one may make mistakes. But the real problem is where the setting isn't quite known. To pick on D&D a bit more (its a big system, it can take it) there are multiple settings it covers an they have different ideas that one rule set can't always represent very well. If you made a new system for Eberon, Ravenloft and Dark Sun I don't think they would be so compatible with each other.
Oddly enough I don't think anyone has. I just have one major question: Is this design intent or did they just realize that things were going wrong before they published the book? Or is awa correct and maybe it is a divide between PCs and NPCs?
On the other hand if martials are supposed to be "a core of martial skills amplified by magic" then maybe it is just a communication thing? Legend explicitly had that as a balance option, you could swap out some of your ability to use magic gear for more skills.
But this means we may have to revisit the older D&D editions to figure out if lack of caster survivability was intentional or not. Quertus might of had a stronger point that I initially thought.
