Unless you love Azir or Miss Fortune, there is probably a strong chance you are starting to get worried that the amount of new champs are appearing much faster than lore events. This is kind of depressing.
I don't think that's all that accurate. Sure the lore updates are slow, but multiple champs are be involved in a single lore event at the same time. Blidgewater alone had TF, Graves, GP and MF, then shortly after had a new story involving Thresh, Illoai, MF, Lucian, GP, Olaf and maybe more, especially if you count the solo updates champs got for that event. Some of those champs like Olaf hardly even had a real reason to be there but were still added for one reason or another. Then there are champs like 
who add new stuff for other champs like in this case 
and 
.
Then from the sounds of things Riot is planning a MASSIVE lore event that will likely involve multiple places at once, meaning content for a lot of champs.
So even though a new champ is technically coming out every 2 months (give or take depending on their new system) and lore events were taking 3-4, Lore events still cover quite a few champs at once and Honestly even this year there has been more lore updates then champ releases as a whole (Demacia event, Vastayan update, Piltover/Zaun to name a few). I believe once Riot gets through updating all the champs base lores, we will see more varied events covering many more champs as they will have the time to focus on larger stories since there will be no more champs who need to be retconned into the current lore.
TLDR at bottom.
Some champs would be hard to fit into a story line but pretty much everyone can still contribute. So far all of the lore events are area based where a lot of characters share the spotlight and interact with each other. Shurima w/ 
Bilgewater w/ 
. If you wanted a story with 
or 
it would be kind of hard to write other people in so some characters are going to just naturally get more lore spotlight. and 
have a story where they fight each other but other then just hunting stuff what else does Gnar plan on accomplishing? Plus how do you write a good story with champs like 
or 
? They can't really talk or interact with other people so how can they have major story contributions? Fiddle could have a thriller style story, which could be cool by itself, but how do you possibly connect that to major events around Runeterra? How would his character have any kind of influence on the other champs?
However I think there is a TON of stuff that can still be done in the Lore to include pretty much everyone and make for really good stories! Right now in the lore they actually have quite a bit of stuff set up that could include so many characters.
My favorite open story line is 
, who is being pursued by 
and 
[possibly as well as any of shens disciples 
], is on his way to Zaun. And because Piltover is so close to Zaun, In Zaun he could possibly interact w/ 
as well as and if they have shown up to Piltover yet. Jhin said he has something big planned but we still don't know exactly what it is or who is going to get caught up in it.
The other big one that could include pretty much any character if the story team tried hard enough is the void invasion. Right now Targon as well as others are setting up against the void so 
all have potential. And the void's main forces could choose anywhere to attack. They could attack Ionia and get 
in the mix. Or just as easily go after the Frejlord and we could see any of these champs: 
.
Demacia vs. Noxus still has a ton of stuff it can do with: 
as well. So I think a lot of champs can be included when they do have the next lore events and including a ton of characters could easily catch up and involve everyone in some kind of big event.
TLDR: Most champs definitely have story potential and only a select few don't. Riot writes stories that include entire areas with multiple characters interacting with each other so we could definitely catch up and include mostly everyone in a couple major story arcs.
And while some people complain about champions who even got reworked recently , i'm just sitting here , with champions who litteraly haven't got their lore changed one line since the release of the game itself.
Some champs are never meant to go further with lore, but I still do hope riot updates the lore of older champs.
I actually find that very concerning. I really like the lore of league, and I wish that there could be some sort of serialized story format that would make sure we got to see more lore for more champions. I know not enough people are invested in the lore, and that the quality would decrease with the higher frequency, but it's sort of sad knowing that I probably won't see Nautilus change as a character or know what wukong will do in reaction to xayah and rakan's ideals or see bard interact with someone like ivern or even yasuo. At the current rate of story building that stuff wouldn't come out until I'm 30
I'd rather have more champions than them waste time on lore, I'm playing a moba not library simulator.
