Nidalee, when mastered, is one of the most polarizing champions to play against
Like seriously, ask anyone in high elo. They all HATE playing versus Nidalee because of her power when someone good at her is playing her. I don't even understand how she's considered balanced other than the fact that she takes some brain to play, but regardless, just because she's "difficult" to play doesn't mean she should be a champion you can rarely lose on. I don't even think I need to go into detail about her kit, because most of you already know.
Heck, Rush said this on stream too..
