Honestly? I think the current setup is actually better for the game than when the focus of WotC's money-making efforts was selling D&D books. 3.5's massive pile o' books and 4e's... well, 4e (I loved 4e, and I desperately needed it to renew my interest in the game as a whole when burn-out on 3e hit, but it was a mess and kept growing into a bigger one) were the outcome of WotC needing to sell books to turn a profit on the brand.
Because if you need to sell game books to make money, you're going to keep putting game books out. Quickly - too quickly. And each one is going to need to have something in it to sell it to every group of players, because you need to make as many sales as possible of each book.
Now they don't need to do that. Now, D&D makes money by being something people want to license and use to make other media, and it does THAT by providing high-quality ideas and inspiration and by being a brand that people want to be associated with. "Hey, look at us. We inspired basically the entire fantasy genre. We're objectively the best. Come, pay us to use our name and our IP in your work, for you will profit and we will happily take some of your money to let you."
I much prefer that over Sword and Fist.
I much prefer higher quality books. There were duds. We're getting a lot of duds right now, at least in my group's opinion. We haven't liked much they've put out. No one is excited about the
Sword Coast Adventurer's Guide. Our entire group felt Tyranny of Dragons and Princes of the Apocalypse were lackluster. I do like
Out of the Abyss.
I much prefer when WotC was putting out great books like
Faiths and Avatars, the
Forgotten Realm Campaign Setting, and many other high quality books. Sure, there were some duds. That's bound to happen when you produce as many books as they produced. At the same time you had a lot of high quality material mixed in with the boring.
I guess we differ. I came up from way back in the day. There was huge amount of high quality material produced when making a volume of books. Same as Paizo with all their books. I'm not seeing the effect you seem to think is occurring: lower volume leading to higher quality. I'm just seeing less of a focus on tabletop materials. A much smaller, almost skeleton staff, and generally lower quality adventures and splat books that don't have me interested in spending my money on them. I used to love to buy RPG books from WotC. I'm not feeling that way at the moment.
That "objectively the best" is not true.
World of Warcraft is objectively the best in fantasy video games. There are tons of other video games that outsell D&D. D&D has not made a high quality video game that has dominated the fantasy market in the same way their tabletop RPG dominated the tabletop RPG market. Their making money, no doubt. They're not making as much as they could or should using the intellectual material they have at their disposal. Their movies have been failures, absolute and complete failures, not even close to the best. Their book lines are hit or miss. Their video games have had some winners.
Sword Coast Legends isn't looking like a winner.
Neverwinter the MMO is a weak MMO compared to
Everquest or
World of Warcraft. So we will have to disagree on them being "objectively the best." They certainly inspired the genre, but they've never dominated any aspect of it save for the tabletop RPG market. And Paizo took market share from them to the point they had to shrink the tabletop RPG part of WotC and move in a different direction.
We'll see how Mearls does at keeping the tabletop RPG part of D&D alive and flourishing. So far I'm not overly impressed with their offerings other than the PHB, the MM, and
Out of the Abyss. Doubt I'll buy the
Sword Coast Adventurer's Guide. It's just not a very high quality book compared to what I am accustomed to from FR books. FR books used to be a guaranteed buy. This one is not.
