Nidalee Nerfs on the PBE Do Not Address the Real Problem
The following is currently being tested on the PBE:
Nidalee Base HP reduced to 511 from 541 HP Growth reduced to 75 from 90 Primal Surge (Human E) cooldown increased to 16 seconds from 12 seconds.
I posted about this nerf before (http://boards.na.leagueoflegends.com/en/c/gameplay-balance/ahwk1cA2-nidalee-nerfs-on-pbe-overkill) and got a lot of feedback, and I think I finally figured out how I feel about this: Nidalee does need a bit of a nerf, but this is the wrong nerf.
The most notable part of this nerf is the HP reduction (30 at level 1, increasing to 285 at level 18). That's pretty hefty, actually (80-760 gold value), especially with another nerf thrown in. And to be honest I like the fact that Nidalee adds to jungler diversity by being one of only a handful of truly viable mage junglers, and by far the most popular one in pro play.
In my opinion, the truly obnoxious ability on Nidalee is Javelin Toss--specifically the range-based damage increase. The base damage is 50/75/100/125/150 +40% AP, but that increases to 150-450 + 120% AP at max range (3x damage multiplier). That's better than a lot of ultimates. Now, I understand that Nidalee doesn't have a conventional ultimate, but she gets access to three cougar-form abilities to compensate. And the cool factor of landing a Javelin to trigger a hunt and pounce in with the cougar-form abilities is somewhat lost when the Javelin Toss itself simply deletes the opposing champion.
My suggestion would be to nerf the range-based damage increase on Javelin toss to something like 2.5x. Reducing the AP ratio is another option, though I personally don't like it as much. By the numbers, Nidalee isn't actually that OP (52% winrate in Diamond, lower in other leagues likely due to her rise in popularity), so I don't think a large nerf is needed, but a change like this would take the edge off of her ability to randomly delete people. It would also offer greater incentives for her to jump in with cougar form (since she wouldn't just kill her opponent with Javelin Toss as often) while not further punishing her for doing so (as nerfing her health would do).
I'd be interested to hear your thoughts.
