It would be cool if we got a story arc every game play season.
It wouldn't need to be something as major as a void invasion but having game play and e-sports seasons aligned with story seasons could be really cool. And no I don't mean story affecting e-sports or game play I mean something like at the start of Season 8 we get a chunk of lore that sets up a story line, maybe something with Swain and Noxus through comics, short stories, a cinematic or two, and by the end of the season that story would come to some kind of conclusion.
It would be great to actually have a moving plot and I think it would add to end of season hype! Worlds, ranked ending, a story that has been told over a year coming to a big grand finale. Idk to me it seems like it could be pretty cool.
I might be asking for too much at this point but it could even tie into VGU's and new characters. When a character gets a VGU they don't have to get their lore changed, which upsets people, they could be having story progression instead. Or a character that we could grow to love in the lore for months could become a playable character giving people a strong connection with them and/ or adding hype pre-release.
