Her q is ALL she has for damage. her Takedown(Q) is basically the R of almost every other champion. they removed the damage from her traps entirely! Swipe(e) is only good for farming.
her heal is useless early game and hurts her mana a lot!!!
with her most recent nerfs she has been balanced quite a bit actually. her traps damage is gone, her heal cost was raised. she has lower armor and lower health then most champions now as well.
here are my tips for all who think she is still op. get as close as you can to her. play defensively AKA Dodge Spears. and don't let her farm. if your champion lacks a slow stun or dash you are probably going to have a hard time with that
then here is how you challenge a nidalee as a cc-less mobility screwed champion.
1)buy a health pot or two 2)let her push and 3)call for your jg, pin her down, and sell her remains to a Chinese restaurant.
she is a hard champion to balance but i think riot has done a good job at fixing it!!
