Jarvan IV,Hecarim and Rek'Sai getting nerfs in 9.9
Isn't jungle in a weak state right now? mid lane is up 2 levels on you whole game, the only champions that made it easier were jarvan,hecarim and rek'sai.
While vayne,riven,jax,vladimir and kai'sa are picked every game because they outperform anything they go against. There is blade of the ruined king nerf but that doesn't affect just vayne but other champions too, so it is quite unneeded.
Lets ignore all other lanes and look at the current state of the jungle, you are basically a second support, the only reason rek'sai was so good was because early game is so important and you don't need to farm to be relevant or more like you shouldn't, it is bascailly impossible to pick a scaling champion in the jungle and expect to win against equally skilled opponent.Only reason hecarim is strong is because conqueror works so well with his kit, other champions aren't so lucky.
So the exp in the jungle was nerfed because jungler could get level 3 and gank while your laner is level 2, this was only possible in the early game and because of the leash you get from your teammates. Because players whined about ganks from lee sin level 3 while they are level 2, this was nerfed and junglers are level 4 while mid is level 6 now.
