Their point is about drawing an initial connection between summoner and champion for identification purposes. You know the story. You know the lore now. So it's important to you. But if you take away the JoJ. Talon's Judgment. And just had the bio...
What would you know about Talon as a character? It's basically meant to make it more accessible while open up future avenues for more in-depth storytelling, so it doesn't seem so crammed/half-told it seems like.
It's these interwoven threads connecting the characters that I really enjoy, and I would hate to see it go.
Though like I said, I could be blowing this out of proportion
