I think jungle as a role is too overbearing and impossible to deal with

I thoroughly and wholeheartedly believe that jungle as a role is a gigantic issue for the healthyness of the game. I don't understand why people are allowed to play a role where all they do is gg other peoples lanes. they always have the most gold and have too much damage early mid and late game. Jungle has op item and it 1 shot me all the time. Lee sin q q r just kills me in 2 seconds. he builds statikk shiv and duskblade and he kills me with no counterplay. not to mention eveelynn can perma cc lock me and destroy me in 0.012 seconds (I looked at death recap). jungle gets way too many chances back in the game, they can take camps and soak xp from lanes. They hit level 6 and can 1 shot me and I can't do anything back because even tho my laner is getting destroyed. I think riot needs to nerf jungle xp more so they cannot hit level 6 so early. Also they need to remove jungle taking xp from lanes, it just lets them get levels early and beat me, how is it fair they get lane xp and camp xp??? They should remove xp gain from minions when you have a jungle item, and make the jungle items cost 500-700 more gold. Even sunfire cape jungle tanks can kill me and take no damage. I try to kill sejuani but she just r q autos me and takes 25 damage from each of my yasuo q and auto attacks. I think riot needs to seriously consider removing the toxic role form the game. THe community would much rather not have to deal with a role meant to ruin the others fun. I failed my promotion to silver 3 twice because enemy zyra jungle came and 1 shot me (jungle is so op anyone can play it and one shot). Now I am bronze 1 because my jungler is just afk feeding the enemy and they just come to my lane and repeat camp and kill me. Riot needs to seriously fix their game.
