We've had discussions before - which faction is the best? Whether it's Demacia vs Noxus, or Bilgewater vs Shadow Isles, or "anything except Shurima", people love to root for their favorite factions.
Riot is threatening to dismantle that, replacing it with a cast system.
Skip to 2:45 in the video and you can see what they're up to so far.
You like Bilgewater? Tough luck, Bilgewater is now Ranked worse than Bronze. Your faction sucks, and you can't even argue otherwise because the game itself is going to tell you Bilgewater is at the bottom of the barrel.
This *will* influence how people view the factions, which is why I think this is a terrible idea that needs to be talked about ***now***, not when 2019 is already upon us.
