Why not? Then as soon as you complain about the balance in 4e and cite an adventure to support your position, people can say stuff like "you changed the rules without being as experienced as Mike Mearls!"
And they would be right! I certainly don't have the experience with 4e necessary to change the rules and know that my changes will not have unintended consequences.
One would hope that the designers have enough insight into the rules to change them with fewer problems than the average player/DM would. I would wonder why I am paying for a product that the average player/DM can revise with little consequence.
After all, that is the source of the admonition in the 1e DMG: That you can change the systems if you like, but they are as they are for a reason, and if you change them, it helps to first understand them well enough to know what your changes are actually going to do to game play. (Paraphrased -- I don't have the 1e DMG with me here at work. I am sure someone could pull the exact quote.)
And, while I am sure that there are folks who can change 4e without problems, I have little sympathy for those who make changes, then blame 4e when those changes don't pan out the way they expected!
I mean, look at how many early 4e threads revolved around "problems" that people who liked 4e were not having. 4e doesn't provide what I want, but it does provide its own thing. Not understanding what that "own thing" is led to a lot of poorly-thought-out posts, including my own, which I have little sympathy for in retrospect. As my understanding of 4e grows, my respect for it as a system grows as well. I still don't want to run it, but I can see why people enjoy it. And some of my earlier opinions were flat-out wrong.
Is that the fault of 4e, or is that my fault?
You don't need to answer -- that is my fault.
If you neither follow the rules, nor following module text as written, achieve unbalanced results, and then blame the designers, that is your fault. It doesn't matter what game system it is.
(That the rules in 1e are hard to follow [sometimes in both a literal and figurative sense], though, is Gary's fault. Let blame fall where blame is due.)
Of course, we could also - after trazillion pages of arguing - just agree to disagree, and move on.
We could even, perhaps, do so before we reach a trazillion pages.
