hello, this is the first time i have seen this argument as i dont frequent the forums, mostly the news part of the website. but honestly as fresh eyes on this supposed last word, it just sounds like you might not have a very good DM for you. i understand you think DM's might need to tweak monsters to deal with certain feats or power levels of PC builds, but to me that is the whole point of being a DM. now sure a DM who buys the published adventures and runs them straight with no input from themselves might run into trouble with certain PC's i give you that.
for me, and a lot of people i have gamed with over many years, the DM is not just the storyteller and NPC runner, they are the balance, they are the architects of fun. you have a group who min/max's and "abuses" GWM and SS, the whole point that you have a HUMAN running the game and not some math computer or such, is that humans can design and create scenario's equally challenging to the player.
now if you want a game system that did all that for you and was "balanced" then you wouldnt have a human DM, because when you introduce humans to any situation, by default it becomes un-perfect. sure 2+2 will always be 4, except when a human decides it isnt. meaning a DM can create a world where 2+2=5. i know this is a silly example, but i am basically saying that if you feel the game you play in or run is unbalanced, you have the tools to fix it. you dont have to ban any skills feats powers or anything. if you think magic PC's are too powerful because of cantrips after they have run out of spell slots, the warrior is still going strong. maybe monsters fear magic people and concentrate on them, maybe you run more encounters in a day so the magic user has nothing but those cantrips to rely on. (3 eldritch blasts at 1d10+5 is equaled out to the fighter attacking 3 times, and because of his weapon focus gets +10 damage. kind of equal to me). these are only a small few of many examples of how to deal with PC's. so many tools for a DM to run the game STILL within the rules and yet present challenge.
now if your "final word" really just boils down to, "without DM input the game is unbalanced, fight me" then i would agree with you 100%. unfortunately i have been part of super min/max games where the DM equally challenged us, and in mostly RP PC games where the DM has equally challenged us outside of combat. so i honestly suggest you find a new DM who fits your play-style and understands, or if you are the DM, stop being so lazy.
i'll go back to lurking the news now, but wanted to share my 2cp.
