A list of champions that deserve nerfs more so than Sejuani or Gnar

This is just to name a few, obviously, but I hope you get the point. There's literally no reason to nerf Sejuani or Gnar except for worlds coverage and "diversity" in champion picks. It just shows that it doesn't matter what's affecting the overwhelming majority of the player base in terms of balancing, because that doesn't matter to Riot when they're making big bucks off of their absurdly boring competitive scene that won't be fixed by simply removing one champion or adding another to the competitive scene.
How sad! And they want respect from their community by doing this?
