Is it possible to balance League of Legends?

I've never seen this game in a "balanced" state where you could use close to anyone and be viable if played right, even in the praised late s5 tank meta (It wasn't super balanced!) Everyone always complains that the game is unbalanced but I don't understand how you balance this game when everyone rides the meta. Whenever the current meta that everyone is complaining about gets nerfed because of champions getting nerfed and or different type of champions get buffed, the meta shifts and everyone rides the new one which later results in more complaining because *insert new hot shit champions here and old meta champions are "gutted"* and this never ending cycle of unbalanced bullshit continues. Someone open my eyes, how would you balance this game to where everyone can play almost any champion and not get fucked on by a Rengar or LeBlanc.
