Stories are too short!

Well, with champions like Rek'sai and Kalista, Rek'sai had that Journal from the Noxian Cartographer and Kalista had the Video when her Oathsworn died. So they aren't planning on shortening stories, but they are just expanding it with pictures and moving figures and such. Look at Azir, for Example, he had about 3 videos on it about how he was to come back.

For some reason the mysterious Lore department at Riot, which for some reason we aren't allowed to know anything about, has decided that short stories on the in-game client are better than the longer ones we used to have.

Complete lore will be available on the website soon(*tm).

At this point, it's starting to become obvious that Riot doesn't care about its lore. If it did, it would have been more of a priority and the kind of problems they are having now wouldn't be an issue. On the other hand, they might just be completely incompetent when it comes to delivering lore, and we've just been seeing the results of stupid people trying to do stupid things.

Although I don't believe that to be the case, it is still a possibility.
