Whats with Cho' Gath, Nocturne and Brand without the IoW?

Hey guys, I have a little Question to think about: You remember the Old lore from Champions that could destroy Valoran, but are being put down by the IoW and the League like Brand or Nocturne? Maybe like their Lore gets rewritten completly to prevent these Creatures to destroy Runeterra, to let them appear a little less dangerous? Because according to the Old lore, Brand and Cho just join the League because they were being forced to Join. Think about it. Brand as the ETERNAL, Burning Vengeance cant be simply killed. I guess when the body of Kegan gets destroyed, The Spirit of Brand wont be disappear, it could just simply search for another Body. So killing Kegan would be pointless. And at the moment, Brand is just part of the league because there no real Reason to Destroy Valoran immediatly. Correct me if I'm wrong, I Havent Read all of the JoJ's out there, but what would happen to Cho and The Void at its own without the IoW? It would be Kassadins Job to keep the creatures of the void Inside the Void, and I'm pretty sure that cant stay well when Time passes on. And whats about Other Champions and the battling on the SR for example? Can Caitlyn, who is just a Sherrif with a Good Aim and a Big Weapon, destroy a big Cho? Or take jax for example.Without the IoW, there would be no Contact which sais that Jax has to use a Lamp while Fighting? Just keep that in Mind. Im really Curious because of the New lore, and how Riot treats the Lore of different Champions and expands them. Maybe they'll find a neat solution for this, or they just say: "Meh, lets erease the Lore from LoL". I dont know what Riot is Intending to do, but I have Faith in them. And the faith dies last!
