I will give you 3 reasons why game is in bad shape right, unbalanced and sick to play.

Conquer keystone killed most of champions special Tankers, made having adc isn't a must since your true damage is enough to take down tankers as fighter, killed champions such as cause stacking armor to scale into game is useless now against it, kill champions like since he can't use it to bypass armor while other can use it against him, etc. Infact Conquer did screw the light fighters like etc why you go semi tanky like you suppose to go when you can go full damage + to give you extra HP shield while on other hand if you tried the normal divers semi tanky build you mostly screw by the true damage of Conquer.

Jungle change that made the game more toxic since now jungler can fail badly in game if they got "Bad" mid laner and enemy got "good " mid laner, good mid laner now decide the fate of jungler either by helping them in river or invading other jungler while jungler that fall behind stay behind useless.

Riot balance team doesn't hear people at all, people said going to make problems atleast adjust and make passive doesn't work with passive but they didn't listen on either. People said towers doesn't need more nerfs infact buffs, they just go and nerf the base towers.
