Ok, heh,
@doctorbadwolf, I imagine it comes as no surprise that I disagree with you.
What I've seen in the hobby and the genre is the tyranny of the nostalgic. Any new ideas are immediately met with outright hostility and ridicule. You want to change X? Oh, HELL no. That would contradict some article written in Dragon Magazine in 1994, so, you CAN'T change that. It's CANON.
And the Canon Police are very, very active. Any and all changes get resisted very strongly. Things MUST BE done the way they were before and YOU MUST NOT change things is the repeated refrain, over and over again. Heck, things are judged, not on whether they are actually good or bad in their own right, but how closely they toe the line of what came before.
WotC add Dragonborn and Tieflings to Greyhawk!! Oh HELLS NO. The wailing and gnashing of teeth can be heard all over the place. Make psionics just another type of magic utilizing existing mechanics because it gets the job done and it's much easier to learn? Oh HELLS NO. Not a chance. On and on and on.
Good grief, invoking Tolkien is the fantasy genre equivalent of Godwinning a thread.
So, no, I'm really not seeing what you are seeing. What I AM seeing is 5e, finally, after what, 7 years, FINALLY starting to bang out some original material that isn't reprint or rehash of what came before. Like I said to
@TheSword above, what would you consider to be the first original WotC 5e adventure? I'm thinking Candlekeep, but, I might have missed something. Maybe Dragon Heist - but, then, that leads straight into Dungeons of the Mad Mage which is 100% rehash.
So, what would you call the first original 5e work?
