What we are experiencing is not imbalanced gameplay, rather a result of ranked inflation

Your ranks do not reflect your skill. Your skills are inferior. A silver in season 2 is equivalent to today's platinum, a gold to today's diamond. There are many factors to blame but the greatest blame goes to the community, the players. The ones who wanted ranked to cater to them over preserving integrity, the ones who just want a shiny precious metal given to them over truly earning it.

One of the main things people try to blame is autofill, but autofill was the balancing scale that truly added integrity to ranked. In the earlier seasons, there was no guarantee of a role, you needed pocket picks and to understand the game and your matchups as a whole to succeed.

You can blame Riot for the changes all you want, but there's no denying that your skill was never able to handle things before the changes.
