Would you mind giving me a bit more insight into why the Medarda map disappointed you/pissed you off so much?
It annoys me because when I look at this map, and I see the overload of details and no-name places. These places have no consequence. They don't matter. They're there really just as filler - to fill up the map. To copy paste examples from r/worldbuilding, it reminds me a lot of these.

To me, there's really no difference between Riot's maps here and the ones made by amateurs. It's EASY to get excited and make an overly detailed map and go wild adding random locations without any intention of actually fleshing them out later. They're just names on a piece of paper that exists nowhere but in name. They don't have an identify or an existence. They're just there to make the map look fuller and cooler.
The biggest difference between a map like the ones I linked and say, a map of Westeros, is that Westeros' world is intimately fleshed out either by movie, shows, books, whatever. Each region and culture in GoT is clearly defined and stories are centered around these locations with characters that progress and interact.
League simply doesn't have that right now.
I remember a friend telling me it's pretty common to talk what-if scenarios in Westeros. What if the North and Vale joined in an alliance against the South or whatever. All these armchair logistical discussions. They're fun because there's a plethora of backing that makes the map meaningful from books to stories or appendices. You can talk population densities, where major centers of trade and castles are, and fighting styles...
You can't do that in League simply because hell, we don't even have a full map of Runeterra.
If you ask any avid watcher/reader of GoT and talk about the Westerlands or the North, they'll have a pretty good idea of what you're talking about. If I talked about Urzeris or some random location on the map, even the more ardent League lore-nut would be tough to describe what it's like there. Compare that to how fleshed out Last Hearth, White Harbor and Dreadfort is from Game of Thrones both in terms of fanart, fanfiction, discussions, and etc... Then you realize these are relatively minor settlements compared to High Garden, Casterly Rock, King's Landing and think how well those cities are fleshed out.
So when I see a map like the Medarda map, I kind of see of it as pointless. I know nothing about this region. I care nothing for it. Nothing outside of Piltover really matters.
From what you write here, it sounds like you'd have preferred the map not to have any locations mentioned, except for Piltover? That might be the wrong way to interpret what you wrote. I know Psyrix has mentioned that there are several locations on the map that have been referenced in other contexts (bios, color stories, short stories, and VO) but that's not the sort of thing you were looking for, it seems.
Name-dropping a place doesn't exactly flesh it for me. I noticed in the newer lores, there's a lot more adjectives and name dropping. Taric's example come to mind.
He saw the Alabaster Library engulfed in pitch and flame, and still he dashed into the roiling inferno to retrieve the poetry of Tung. He screamed in rage as the Frostguard ran the last dreamstag off a blind cliff, and then leapt into the abyss himself in a desperate attempt to save it.
This is a problem that's consistently seen in League lore. Stuff gets name-dropped and means pretty much nothing. There's no appendix or wikia to tell me what the Tung are or what a dreamstag is. The Frostguard barely have enough on the wikia to warrant their own section and they share their page with the rest of Freljord.
I would much prefer a story that centers on a specific town or hamlet that gives insight to the culture.
The big problem with this is that this is how it can backfire like it has already happened in Lux's story. The region isn't highlighted at all. The town was Terbisia (had to look it up) and we really know nothing about it except it has walls, got struck with an earthquake and thats it.
Granted, the story is supposed to center on Lux's character but you could honestly replace Terbisia with the city of Demacia herself and the story would gain or lose absolutely nothing. I've learned nothing about Terbisia anyways or its people or its culture.
I think an actually good ( but not great) example in League of providing cultural context is in Jhin's lore.
We hear he's part of a traveling performing troupe and he goes to different places. What's also helpful is that this gives us an idea of the culture in Ionia. We get to see what mere mortals do - they like watching theatre performances and doing festivals. We know they like Blossom Festivals. That sticks with me because it's better than whatever the heck Trebisia was described as.
And this helps me better understand Ionia. If there was a map of Ionia, as I see the Jyom Pass, I could imagine the people there having festivals and celebrating. This is what they do in the course of their daily life. I can imagine the possibilities of other festivals because there is documented examples of the Blossom Festival already.
Now, when I see a map of Ionia, instead of just thinking of a somewhat racist asian-inspired caricature in my head, I can imagine the citizentry in their towns celebrating festivals watching plays.
Am I to understand that, for any map released in the future, you would hope would have an accompanying short-story/encyclopedia entry and illustration for each location labelled? That would probably mean that future maps would be very sparse in locations mentioned due to the time required for getting all that to player-facing quality and approval.
If the released lores are any indication of playing-facing quality, I'm not holding out for much. A lot of Riot's written lore pieces sound purply, excessive use of adjectives, and sometimes feel roundabout.
I do think a short-story encyclopedia entry/illustration for each location would be massively helpful. Granted League isn't an MMO, but World of Warcraft did wonders for fleshing out its world. It's ridiculously detailed. You could look up Northshire, Goldshire, Darkshire... and that's just within the Kingdom of Stormwind. You can read on Westfall and all the struggles of individual places. Just from the name you can get an idea of the culture and the fact you can visit these locations in game is a huge boon (one that League might struggle to imitate like an MMO does).
Can you show me an example of a good map, one that you hold up as an example of what you would want to see Riot do in the future? Not to say that we would follow it, but often it can be easier to understand with a visual aid :D
Really, the only difference between a good map and a bad map is what those things represent. If you showed a Warhammer (or 40k) fan a map of the Old World or the Five Segmentums, they can intimately tell you of each different region. From the Elector-Princes of the Empire to Britannia or the Realm of Ultramar and Cadia and Fenris. All these places mean something on the map.
They're not specks of nothing that serve as space-filler like the Medarda map.
