Completely Unbalanced game

Hello, first of all i would like to say that english is not my first language so I'm not good at it,so please forgive me. Okay,here's the thing why am I writing this. I play LOL for a 2 years now and i feel like the game is NOW AT THE MOMENT completely unlabanced and hard to play. The new jungle items does so much work for you as a champion if you buy it and it's super hard to play against it. For instance: I am ADC and i do have xin zhao jungle against me, he buys the new Devourer item and he instatlny kills me with ONLY this item. Then he can build tank or some more dmg/AS and he can kill everyone. I mean nowadays for ADC and Midlane mage with no escape MAINS is so hard to play against this,even if you are fed,they keep killing you so easly. Next new item-runeglaive is like the same=you keep dying because this new jungle item is so OP,that you can't do nothing about it. AND some champions are really op not only in jungle(ezreal,diana etc..). All i am trying to say is that LOL is unbalanced because these new items..Yes i know,RIOT wanted to increase jungle roles,but isn't it TOO MUCH? Yes, ADCs were strong but it's point of that role,same as midlane,you need mechanics and stuff,but how are u supposed to do something when you are against xin,warwick,shyvana,ezreal,diana (with smite and one of those 2 "upgrades")? Most of cases you can't do ANYTHING about it and you die instatnly if they walk up to you. I think this game needs to be more balanced and not unbalaced like now. Thanks for reading, I hope this post will not get hated too much, I just wanted to tell my toughts and feeling about this. Thank You once more, FrAx0
