This might be an unpopular opinion but I don't get the hype around jinx.
Don't come after me please, lol. It's just my opinion.
First of all, I don't hate her it's just that I do not feel that level of attachment with her that most people do. She is a well written character but she just pmo sometimes, i am sorry.
Vi was my fav in Season 1(still is). That's why it stings so much that they completely sidelined her development and mishandled her character in Season 2.
Again, I don't HATE jinx, I just find her meh and that she wayy Overhyped. I am not a kind of person who interact with the fandom very much, but I still remember being called a 'Trash' for not liking her. Some dude literally went on saying how I am a disgrace to the fandom (no, they were not joking)
I found other characters more interesting, like slico, that guy was masterfully written, and jayce in season 1. I also wished that ekko had more screentime, get to know a bit more about his ambitions instead of getting a straight up gary stu they made of him in S2
EDIT - sorry if my post offended you but wanting better, more consistent writing for a core character isn't being 'MeDia iLLiTerAte' it's expecting the story to treat its protagonists with equal respect, and I will say this all the time, S2 was way too rushed.
