Why have the latest champions IN GAME lores been done so... lazily?

With the last two champions and the lores that were updated from the Shurima event, it seems like they didnt even try... Previous champs have a large page devoted to their lore along with a quote from them which lets you really get a feel for who they are, what they are doing in the league, and a general idea of their motives and personality. However since the Shurima were done so poorly. Which doesnt even make since because they wrote and came up with huge amounts of lore for and even but yet they didnt put ANY it in game. Xerath and Azir have a very rich back story that people would love to read and know but it is left out of the in game lore pages. Azir's in game lore is only two sentences.

I know they made the videos about the story and wrote them else were but not of it is carried over to in game. For new players or people who missed these videos they have no way of knowing the lores of these characters unless they seek it through outside sources. And some of it could have been done as easily as pressing copy paste. The lore that was created has been fantastic but I dont understand why it is being left out of the in game lore and have not been done like every other champion. I wish a Rioter would read this and respond but its unlikely, so any discussion is welcomed and encouraged.
