Nidalee doesn't need to start W to clear early. W is often ranked up at level 3. Starting Q is more reliable because it is resistant to invades setting off your traps and ruining your first clear. The double reset will remain, only slightly weakened.
Look, I agree with the direction of Riot's nerfs. I fully support the heal nerf, as I have played many games where i have ended up TRIPLING the 'healing done' of my Soraka, and that is just stupid. Her heal is too powerful because it keeps her healthy too often and allows her to invade almost all junglers with ease. What I don't agree with (or more so, don't like) is the cooldown nerfs to her cougar abilities. They will slow down her early clears for sure, but they don't remove the fact that a fed Nidalee can still evaporate camps with spear, leap, swipe, takedown and repeat. This and the fact that she will still be able to kill squishies in a simple rotation of her cougar abilities without needing to mark them. A fed Nidalee will not need to wait for these longer cooldowns.
I would assume however that is the direction Riot is trying to go. Make it harder to become a fed Nidalee (since atm it is guaranteed every game) and reward Nidalee players for getting fed.
The nerfs I suggest make Nidalee weaker if you are unskilled, inconsistent, or are versing good players. I guess that idea just seems a lot more attractive to a Nidalee main.
