What happend to the lore?

If we look on the Lore of champions such a Azir, Rek'sai and Kalista their lore seems none existing there is little telling who they are where they came from or any thing there is also no Quote from the champions for instance if you look a Gnar's lore there is a rich inverment telling who he is and where he came from so Riot i hope you can try to fix this because i for once do care about them and a lore will give them a better face on more interaction with the player
