Maybe this is not the best nidalee guide for you, but this is what i see is better if you are spear spamer like me, let me show you how its work for me with Pros / Cons :

Pros:

- high dmg spears, you may take some gnoms with allmust one shot.
- good farm in cat form 6+.
- great anti-farm / lvling agints the enimy team
- work good for solo and mid lane
- good mana control
- cool heals mid / late game

Cons:

- you proply do the top dmg in the target by your spear but u dont get it even as assist sometime, " like u shot u hit 50% from his health after short time out of combat someone take the rest of his health.
- not good for to be in the front in team fight due the dmg u take is high, stay behand spam ur spear / heal, unleas u have good chance to not be targetble so u cat form.
- some ppl dont like this style in ther team " they think u are usless - trust me your spear the hightest dmg in ur team".
