Lore I'd like to see.

I want to see more lore about characters we already have. I get the appeal of new character but the characters that exist need more than to sit around static in the universe while we fight over and over again. Champs need to fight, old versions need to be injured, go into hiding to train, and come out 'upgraded' like Ryze or Trist.

The shadow Isle needs to be attacking, people need to be fighting back, and champions on both sides need to fight each other. And the winning side needs to get a new Champion. Or kit changes or what ever. You should introduce new champs with existing champs interacting.
