Riot no longer holds champions to the same standard they did when they reworked Nidalee in 4.10
Lane Nidalee was fine (maybe a tiny bit too strong) until 5.2 when they broke jungle Nidalee which already had a 50% winrate by making hunt proc on camps.
5.2 through 6.21 Nidalee received 15 nerfs and 1 buff because Riot would not let go on the 5.2 change.
All of those nerfs is what effectively killed lane Nidalee, most of the nerfs were arguably not needed if the 5.2 change was dropped.
I feel like Nidalee has too much power budgeted into diving and executing. You can't even deal 500 damage to a tank with 3k HP with a max range spear.
There was once a HUGE Nidalee fanbase, now it is about 1/10 in the size since all of the changes Riot has put forward alienated the original Nidalee players.
If Riot wants to end the downturn League of Legends has been experiencing for a few years now, they need to revert changes they made years ago that made players quit the game.
All of my friends have quit League of Legends, or still play but would not recommend the game to others because Riot has been shoving and cramming so much crap into the game since Season 3.
