The whole lore is just done awfully.
Most of the champion bios are old, and the ones that aren't are disgustingly short. This wouldn't be a problem if Riot were to release content more frequently, but it seems like the lore is tied mostly to champ releases/reworks (which means waiting months for updates). The champs who do have more than a paragraph about them actually have quite a bit of lore, that is, if you can find it. Unless I'm mistaken, there is no official archive for the lore pieces they do. All these problems are multiplied when you realize YOU BARELY KNOW ANYTHING ABOUT THE WORLD THESE STORIES ARE BEING TOLD IN!!! Most of the things about the world I know are based on assumptions from the old lore.
It's even worst if you're new. Most of the basic info about places in the game where things take place is learned through in game hints! Not to mention the confusion caused from the mention of the completely irrelevant "League of Legends" (which is hilarious considering that's the name of the game) in older champion bios.
To sum things up, here's
's lore:
Once a mortal man blinded by his own hubris, Azir has recently returned as an Ascended being with unmatched dominion over the burning sands. He seeks to restore Shurima to its former glory, but some dispute his right to rule them. Azir’s power, however, is undeniable.
Not a lot right? Of course you're probably saying "But Bob, There's much more lore on him if you go to the wiki!", and you would be right. The problem is that if you look at the page on the website, this extended lore or a link to it is nowhere to be found, so without this knowlegde, I'm stuck thinking "Omg this new lore sucks. Why Rito D:".
