According to Champion.gg Nidalee is the worst champion this patch.

Look at her winrate, I feel bad for her. She should be buffed in many ways to come back to viability:
Passive: Hunted enemies are now silenced and the root now works on champions (to prevent them from retaliating/running when nidalee jumps on them)
Q: Spears can now apply on-hit effects (great synergy with lichbane will help nida in many ways).
W (Trap): Change trap damage to 5%/10%/15%/20%/25% (+ 5%/100AP) max health, she needs a way to deal with beefy tanks.
W (Pounce): Make the cooldown 3 seconds again.
E (Heal): Attack speed is useless on nida, make it 20 / 30 / 40 / 50 / 60% damage reduction for the duration instead. E (Swipe): Deals triple damage to minions and monsters (This will help with her lacking waveclear and jungle speed).
