The History of Kha'Zix
http://ddragon.leagueoflegends.com/cdn/img/champion/splash/Khazix_0.jpg Chapter 1: The Prime Time Ah yes, back in the day of his prime, Kha'Zix was the must ban. An extraordinary jungler who even Rengar feared to duel. He would jump into lane, eat your face, and disappear like nothing of it. This continued for many patches and how the community did complain. Eventually, Riot saw this big ol' bug was making issues so they said to themselves "Alright, lets nerf it." So, they nerfed the living shit out of the Kha's jump Bonus AD ratio. Kha'Zix was still extremely powerful. Riot was confused since Im pretty sure they were sure such a huge nerf would do Kha in, but it didnt seem to be enough.
Chapter 2: The Fall First, they attacked his Q, reducing it's missing health bonus damage for Isolated targets when evolved from 8% to 6%. That was all good and dandy, but it didnt seem to be enough for he was still eating people. So it began, the fall of the bug. They increased the Isolation radius till it began to border Gangplank's ultimate AoE radius for how big it was. They then made turrets count as units for Isolation and increased the window that Kha could be seen during his R in between casts. Kha was beginning to be in a balanced state... or at least they thought. Kha dropped off the face of the earth and was never seen again. They buffed his E cool down, but its cool down was still dreadfully long. They noticed Kha's abysmal stats and such and so reworked his Q... but then they realized it turned out to be a nerf overall since the missing health damage was removed and the base Q without being evolved was nerfed to a terrible state. They increased the slow and damage against monsters on his W (which didnt help all that much in the long run), but then they did something that killed the bug. They removed the 50% damage reduction during his R by evolving it. Kha'Zix almost completely disappeared after the initial batch of people trying him out with the changes. He was no more. They buffed his Q a bit, but it wasnt enough. Kha'Zix mains were in ruin and they were forced to find more unconventional ways of playing the bug. They brought him into the lanes and began to use his W as a very good poking tool. They were doing OK, but the eyes of Riot saw this and forsake the playstyle as an annoying poke play style. They nerfed the higher ranked damage of Kha's W by a decent amount, but really killed it two patches later by increasing the cool down to 10 seconds from 8 seconds, an effective 25% increase. Riot realized that they had just destroyed the last way to play Kha it seems and slightly buffed the radius of Isolation to make it smaller, yet still no where near it's glory days. It was not enough however.
Chapter 3: The Bottom of the Bottom Change is... not good at all it seems. Kha'Zix lay on the bottom of the champion pool, rotting like the bug he is. Riot has recently tried to bring some life back into the bug by buffing his armor by 3 and reducing the mana cost of his Q by 5, but the bug has not even twitched to acknowledge such buffs. So, what did we learn here? Dont nerf the useful part of every single one of a champion's abilities. Then you get a skinny, starving, probably dead Voidreaver that only appears when he is lucky enough for one of his mains to bring him light. Whether he performs well or not is up to the match however, seemingly losing majority of the time anyway.
Thus concludes the story of Kha'Zix, the Voidreaver. Indeed, this piece of League history shows us the absolute worst outcome of Riot's nerf hammer and probably also the worst way to nerf a champion. Have a happy day... unlike Kha.

to protect me for example (to allow Kha'Zix to survive their damage). Other assassins do not need tank items; they can build full damage because their target will not be able to fight back on the first place.
and faught and now wants to assimilate him badly
chapter4: blah blah blah buff him so he can eat
are my nostalgia champs as they are the first champs i bought in this game to start with.
