Capitalize on Janna's new lore!
I don't know if the right people are going to see this, but I'm putting it out there.
Janna's recent lore update was one of the greatest shifts in backstory I can bring to mind. She went from an orphaned child from Zaun made famous for her windy talent to a benevolent wind spirit born from and empowered by belief.
Seeing as how the entire nature of her existence changed, I cautiously propose a visual update to be in order. Not only are most of her models and animations pretty outdated by today's standards, but now they seem ill fitting for a being of her nature. At least by my tastes, that is. I think with her new identity she could be made into something a lot more than a lady with impractical armor and weird flowing tails. Maybe do away with plate armor and deck her out in some majestic, flowing ensemble with a blue bird motif as a nod to her new origins.
I don't know if Riot would really want to siphon the resources into a new Janna on the whim of some dude on the forums, but hey, I gotta ask for a breath of fresh air for my main.
