I agree. I think it ties back to the mindset that a "proper" fantasy story has to be a knock off of LOTR, GOT, or D&D.
I agree. Part of the reason I stopped reading fantasy for a long time is because people made it too complicated, both modern and classic fantasy. If you have a major goal of the story, talk about that. As a reader, I want to know about that. I want to care about the characters. I don't want to stop my train of thought over plotholes created by magitech. If you invent magitech, let it work in a way that people recognize and make it normal. If everyone can magically fly/teleport, why would they need a train? Why would they need floo powder to travel?
The only situation I can think of from "classic" fantasy is the scene where someone has to sneak out in the middle of the night and rendevous in the woods with someone who has horses for them.
That's why I advocate for more tech even basic inventions to make people's lives easier. Carnival Row has all sorts of magical creatures but it's set in a pseudo-Victorian Era fantasy world. There are lights, indoor plumbing, trains, etc but the gentile, upper-class folk still ride in horse-drawn carriages. The whole house might not be heated but they have more options for heat than a firepit and more options to bathe than a large wooden tub.
The core of this thread and people's comments seem to be that fantasy doesn't have to be overly complicated. You don't HAVE to start from scratch with your worldbuilding. Any location/era will work as long as you do your research.
It's not just the historical fantasies that fall into the overly complicated trap. If you step away from shifter romances, how many dystopian stories are there where the MC's family is impoverished and are at the mercy of complicated governmental plot point for support? Depending on the story, simpler plot elements make more sense to carry the story forward. Like @HGohwell, I believe, said, people like to invent and tinker, so less is more worldbuilding works here too.
