Problem is that Riot performs only Surface fixing rather than addressing the Underlying Issues.

It's like the mythological story of the Hydra that when you cut one head two more grow.
This is the current modus operandi Riot is practicing.

It's like there isn't enough work to do so they fashion work, by breaking their game.
Riot's Balance Team is afraid to give you a great game because if they did they'd be out of a job.

Way I see it maybe a better system would be to pay your Balance team such that they get like a royalty on their work so that it has lasting power.

You could pay them less overall, but that's okay because they would have more freetime to make money doing other things with their talent, as well as grow/expand on their talent.

Example: years later a successful musician can continue to make plenty of dough if their album was successful for years after they were actively making and doing concerts etc. So in this manner, if the game was successful for years and largely unchanged since it was fixed.
The devs would need to properly annotate all the fundamentals that should stay in place or only replaced with other fundamentals. As longs as he(r) was / they were correct in their assessment/evaluation of what order of importance the game's design should be in, then they should have this lasting stake in the game's ongoing success.

That way they and everyone can move on to better things and enjoy an existence where they can sample more things that life has to offer than to re-encounter the same old problems only temporarily & haphazardly treating them, not identifying root issue never really moving on.

Devote more effort to cutting the problem's head only once with a searing blade (at the base) so as to prevents the growth of other heads. We can do better. If there's a will there's a way.

@Meddler and rest aren't you all tired of this never ending cyclical madness.
