@Riot: fret not, I have solved jungling.
In a feverish dream of supreme revelation the outer gods have bestowed upon me the Eldritch truth about why Riot's best efforts in dealing with the jungle by nerfing it in the past 4 years have utterly failed.
Getting a kill nets more experience and gold than any camp.
As a result, a successful jungler doesn't need to farm, and can focus on ganking. More successful they are, easier are their subsequent ganks, thanks to damage meta and runes reforged.
If kill exp was severely nerfed, successful junglers would still need to farm, because they would have the gold but lack the exp.
On the other hand, making farming the jungle harsher and less rewarding for everybody has only the effect of pushing more and more into the meta those usual earlygame junglers that excel at ganking and have the tools to be successful and access the superior form of exp+gold income.
TL;DR: gut kill exp, nerf strong junglers, buff jungle
You can thank me later. I have conceived such advanced analysis only because I am genius and prophet.
