the new Rule of Three is up
I think that the golden tidbit in the answer to that question, regardless of the fluff vs. crunch disconnect issues, is that the system they used is about choices. I find that immensely more satisfying as both player and DM than a mechanic that says, "you MUST do this."
Taunting works for WoW, but in D&D, the mark mechanics are much better, IMHO. They made the right decision there.
The first is that I would have never guessed that "sim" was a priority when it came to 4e's mechanics... second because it kind of implies that even the developers/designers of 4e saw a difference in what should be accomplishable with mundane vs. magical means... and lastly because it also indicates an assumption that the martial keyword is suppose to be mundane and not a sort of magic as some have tried to claim.
The default explanation for the martial power source has always been mundane - it represents skill and training that allows a seasoned warrior to take advantage of the right opportunities in combat to deliver powerful special attacks. (Hence the name Expoits - they exploit the right circumstance to deliver their attack.)
Now, for many, that was too narrative driven and left holes open that could hinder their suspension of disbelief. Many folks have come up with or used various other interpretations, and that's perfectly fine. These include everything from certain attacks taking extra effort, to the system being driven by some sort of chi or similar energy, to it representing superhuman or supernatural magical ability.
But that was never the official explanation, and those who were using that as a criticism of the system were always pretty much just... making up stuff (or failing to understand stuff) in order to have more reasons to complain.
Actually I saw more 4e fans claiming that the martial keyword was never explicitely defined as mundane and that there was even a sentence cited from the PHB concerning this... so no it wasn't detractors I saw who claimed this, it was mostly fans. which is why I find it intersting.
