Lategame I feel so useless as Nidalee

Before, with Strength of Ages + Old Rylai's I'd hit about 2700ish health at level 18, this made me beefy enough that I could make a play without being popped like an absolute grape by the aoe, then executed by any revenge damage. The slow that Rylai gave provided me with some utility lategame, with it I could get into non-Fog of war spear throwing distance against a grouped team so long as I played with caution, now I end up lobbing spears that fizzle out 100+unit away from their target since I fear that should I get any closer without flash, someone will hard engage onto me and that'll be GG. An old Rylai's spear could be just as good as a Morgana binding when landed on a priority target and when capitalised on, now it's not even that impressive. It's just poke, even with a full AP build you'd be lucky to do more than 60% of a squishy targets health with a max ranged spear even if you were two levels above them, and you can't land them reliably enough on account of their missile width, low speed, and the fact that tanks can face-tank them with little to no drawback, so lobbing spears all day isn't a particularly worthwhile or effective strategy.

Before I could actually duel champions if I got the jump on them 1v1...nowadays though I'm getting outdueled by level 14 to my level 16 lee's, while other champions such as Xin Zhao just straight up cannot be fought unless they're horrendous players or oom.

Lategadme I lob spears and hope that someone steps fatally, retardedly fatally, out of position - that or I bait the enemy team into a bad fight and die in the process. That's all I can hope to do, and her Early-midgame obviously isn't nearly strong enough to make up for her horrendous lategadme. If my team isn't playing decently then there's virtually nothing I can do as come lategame I'm virtually powerless.

Kit aside, Nidalee has received continuous indirect nerfs through itemisation and masteries - changes to ROA, nerfing of Zhonyas, changes to Abyssal, changes to Rylai, nerfing of RoA, removal of AP bonus from blue buff, removal of Strength of Ages, the fact that more people are running Thunderlords now also sucks for her as her biggest enemy has always been burst. Then there's the meta - Kha Zix, Lee, Rengar, all of these absolutely dumpster Nidalee. Assuming both players are of equal skill and are displaying equal proficiency at their respective champion, Nidalee won't stand a goddamn chance in hell against any of these three. If you're getting beat by current Nidalee as any of these three then either the stars aligned, or she's just playing considerably better than you - which isn't that much of a surprise considering that anyone still playing her is probably passion picking her. Then there's champions like Xin and Vi who, even if Nidalee manages to beat them early, will take a massive turd on her mid-late should she cross their paths.

Then do I need to mention how much she's been nerfed? Since her rework in 4.10 she's received continuous nerfs, with some paltry buffs in-between (perhaps the most notorious of which is the change that allowed her to mark jungle camps, which shoehorned her into her current role). Top Lane Nidalee is basically dead. For those of you wondering, here's what Nidalee used to have;

Her pounce would reset her Auto timer. Switching between forms would reset her auto timer. Her Q could have a maximum of 333% AD scaling at all ranks, now down to 206% at max rank Her Pounce would have a flat one second cool down when reset (not reducible by cd, but was the same at all ranks) Bushwhack used to do 18% +2% per 100 ap current health damage at max rank. All of her cougar abilities had a 5 second cd. Her heal had a 50% ap ratio at all ranks and a 205 base at max. And most notable of all, if you hunted a target - i.e landed a spear on someone, all of your cougar form abilities would reset. This meant that you could Cougar form W> E> Auto > Q > R> Auto > Q (Spear) > E (heal) > R > Auto > E > W > Auto > Q in one fucking rotation. You could even mix more autos in if you really wanted to.

Since her rework Riot has nerfed Nidalee, shoehorned her, simplified her, dumbed her down, continuously removed mechanics and then continued with their nerfing afterwards. Before Nidalee used to be effective in three roles, now she's only effective in one - a la 43% win rate type of effective. Before Nidalee used to have a variety of attack patterns, but with each passing season her attack pattern becomes more binary, closer and closer to; Land Spear > Jump > Drop Abilities ???? Either did enough damage to scare her opponent, or didn't do enough and is about to get her little cougar ass beat if she can't run away fast enough.

Can something please be done? I don't want Nidalee to be FOTM, everytime she goes FOTM she becomes oppressive, receives a ton of hate, is subsequently nerfed and gains a bad rep. I just want her to have strong points that aren't better achieved by every other damn champion - a reason to play her outside of the fact that I like her.
