I'm actually a relatively new player, and I'm very casual at that, however, when I heard about the journal of justice, I jumped at the chance to learn more about this game and it's characters, I read every single issue. The JoJ gave a great out-look on the world of Runeterra, provided great comedy, and gave us things to anticipate and hope for. Now, we're getting a possible spoiler for a new skin and/or champ in any video (Haven't seen one in the last two by the way.) most of our new champions have very little actual character (Yordle savages, while adorable, do not have much to say, thank god given his voice.), and all of our old champions are being boiled down further into clichés, that Riot already turned down a long time ago. Amumu, was suggested to be a dead human child in his originally planned lore, they turned it down because it seemed too messed up to them, and they wanted him to have some light-heartedness as a character. Before you say anything, the end of the new story actually confirmed it's internal one as truth, or due to mistakes implied it way too strongly.
Also, the safest assumption, currently, is that the narrative right now, is composed of individuals who were brought on board by Tommygnox. Although Abernathy was not a bad writer he did have a history of disregarding the fans of an established universe in favor of his own vision, this appears to have been passed down, but since Abernathy already left due to community outcry, Riot most likely cannot afford to replace the narrative team, AGAIN. However, it is wholly irresponsible on their part of not at least enforcing some guidelines to the lore, so that it retains its common themes (Gameplay connection, Summoners, uncommon Champion interactions.). This entire situation is as if we as the fans of the lore are the oldest child, Riot the mom, the lore our favorite toy, and the narrative team is the youngest who just broke our favorite toy because they can't respect "things" yet, but because the mom is too focused on other aspects of life, she just can't give a shit about it anymore.
Ultimately, with all the yelling and the screaming and the anger, I really just want to know the writing credits of our new "Narrative" team, that is a reasonable request, despite what anyone would tell you.
