The story of Jax
In most of online games , there's a stories and one of the best game stories is world of warcraft but it seems like they ruined it after the death of Arthas , so rito don't ruin League lore you release Jax and put a stupid lore and didn't edit for 6 long years.
Make the point on letters , you rework/edit lore of new champion and forget the old champions like Jax , i hope you will consider making a legendary/ultimate skin of jax and edit his lore like "Who jax truly is" example his skin might be Reginald Ashram or call it "High councilor institue of war - Jax" or something.
2nd most intersting story is Yasuo/Riven lore , i gz you for that its epic but the rest of lores its complete garbage and maybe consider making cinematics.
