What they came up with to fix didn't line up with what most people thought D&D's actual problems were. If Noonan was the only person coming up with this, then Noonan got it wrong in a big way. If this was the genesis of a new edition, it's not surprising that the edition that grew out of this was divisive. Not everyone agreed with Noonan on the problems that 4e needed to fix, or how 4e fixed them.
I don't think I really agree with this.
People at the end of (official support for) 3e understood many of the flaws of the game's design. They understood that the class tiers, while semi-intentional, had done pretty severe damage to the play-experience. They understood that Vancian spellcasting was incredibly overwrought and overcomplicated, while at the same time being heavily abusable by players. They understood that PrCs were busted to hell and back (hence the
vehement opposition to anything PrC-like being added to 5e, because the well is so thoroughly poisoned that no one is willing to let WotC try again). People knew that high-level 3e was
terrible to run, being incredibly DM-intensive without actually rewarding the DM with much freedom. People knew that the Full Attack concept had sounded cool, but ended up being an albatross around 3e's neck. Etc.
A lot of 3e's problems were known and understood. And a lot of the solutions are pretty consistent; there's a reason people who have played both games draw comparisons between 4e and PF2e.
Unfortunately, it just really is the case that some people are attached to...frankly, busted mechanics. Being able to be the star of the show. Being the god-wizard, who
elects to allow others to participate because that's more fun than just solving every problem yourself. Being the insanely powerful shapeshifter-spellcaster-pet-owner. Etc. And, on the flipside, some people are so used to slapping patch after patch after patch after patch onto their game, they no longer see that activity as reflecting that there are problems with the underlying system; they see it as just the cost of doing business.
4e certainly failed to proselytize well, and its makers had such a bad case of foot-in-mouth disease, you'd think they were trying to devour their own femurs from the bottom up. And, as I've said here and many times elsewhere, 4e was
plagued with both unforced (self-caused) and uncontrollable (externally-caused) problems that practically never seemed to let up.
It would always have been controversial--slaying sacred cows is like that. But if it had prevented the formation of Pathfinder (or, better yet, gotten Golarion as an official 3rd-party setting for 4e), straightened out its own act, presented itself as
looking and feeling like a traditional D&D game even though the rules worked differently, prepared better for an incipient and extremely severe recession, and prevented the tragedies and unwise choices that repeatedly doomed the digital tools...I really do think 4e could have overcome the opposition it faced. A lack of organized resistance would have left a lot of players sticking with D&D because, as different as 4e might be, it's not AS different as something like World of Darkness or Shadowrun. It still has AC and attack rolls and six stats and modifiers and familiar classes etc.
One person's cheering is another person's poo sandwich.
The tribe has spoken.
Okay? I have no idea how this has any relevance to what I said. You're talking about the reaction AFTER. I'm talking about how WotC would have viewed things BEFORE. They were getting the right signals early on. People were positive about the changes, and positive about the way WotC initially presented those changes. So they continued doing what they were doing, because people responded positively at first.
That ended up being an unwise decision. In your words, "the tribe" changed its mind and spoke differently after a while. And at that point, the deed was already done. What had once been "do what the tribe says" became "you have done the opposite of what the tribe says
now".
It's part of why I'm so skeptical of the crowd that basically says, "Yes, 5e should absolutely always do exactly what they're currently doing and never, ever change despite the massive changes to D&D's player demographics." In times past, WotC
has listened. And guess what? The tribe was fickle and inconsistent. Democracy is like that. The madding crowd is not required to be rational and sure as hell isn't required to be consistent.
