Just kidding. I'm a Bronze 5 noob that usually carries every game I play. This new ranking system that riot made is rather stupid, but whatever.
Jungle Nidalee is not incredibly difficult, however if you do not know the sequence in which to farm you will fail miserably. So all that I am really going to tell you is how to do that... Since almost everyone already know's how to play Nidalee... right?

You MUST get a leash on Blue buff and get it. After that I usually go to wolves and then get raptors, then ganking starts and you can farm when you'd like.
The process for farming in the jungle is elaborate and complex. Hit with spear, tiger, leap, q, e, human, heal, repeat. sometimes you can get a second leap in after you use your e, but it's up to you. When traveling from camp to camp, you will need to be healing whenever you can. As you can probably tell, Nidalee will have a lot of sustain in the jungle with her heals, but she still needs her blue to do that. More often than not, I never even get red buff and just spam my abilities in the jungle, and only gank if I land a spear, or if my laner does manage to cc them so they cannot fight. If you can time your ganking time and farming time correctly, you can get the full trailblazer with magus enchantment on your first back, and believe me, they will fear you the rest of the game.
