The angels

Any reason riot hasn't touch more on the back story of Morgana and Kayle? Morg is used so much in the game now days yet we know nothing about where she and Kayle come from. No champions have followed them out of this mystery land of theirs. I would love to see some new angel warrior who could stand on the front lines waiting for the day to show their worth. I know ritos got alot going on but don't forget about the things that haven't been touched it a while ;)
