Don't fix what isn't broken in the first place

Title says it all. I've been playing since s4 and I think that one of the biggest reasons of why there is so much commotion about damage/defense or what not is that Riot is "fixing" what ain't broke in the first place (Adding massive buffs to certain champs, items. Massive nurfs to adequate win rate champs, items etc.)

...That leads to more chaos without more clarification from the community and Riot as a TEAM.

"LCS" or "World championships" can't make a game balance which involves MILLIONS of players and not millions of pros....There are only a few of them.

Is this the league of legends for only the pros or for everyone?
