Every change sounds to be an over buff or over nerf

I rarely see changes where people go "Good job Riot" it's either "This champion is fucking broken raa" or "What's the point in playing this champion when these champions do what this champion can do and so much more" or the jungle is too hard or tanks aren't viable (once upon a time, tanks weren't viable) it's just constant complaining, complaining, COMPLAINING.

Almost every change sounds like Riot sort of just guessing stuff off of very little talk with other developers and pros and just over estimating numbers on what needs nerfing or buffing and instead just creates a new problem out of an old problem rather than removing the problem.

I'm curious about two things

1. Is there an actual solution to make this game well balanced and not have dozens of problems like it has right now?

2. How much does Riot listen to the pros about what they think on current meta champions and builds and what they think needs changing?

Do you guys think that Riot just over estimates their changes and doesn't asses them properly? Or is this game just ruled by Meta and nothing is really overpowered it's just the meta making people think stuff is broken?
