Tyler. One. nuff said.
But I'm going to say more. You aren't actually correct about anything you have said including being rank 16. all the players on the top 100 are diamond + for the most part except a couple platinum exceptions.
https://gyazo.com/6a540db90d168cc9f04cfecb1e6d5470 here is 14-20 ON NA you are not anywhere near as good as any of these players at Quinn. Also notice how a lot of these players are not Quinn mains but have insanely high win-rates.
Also on Champion.gg which is a commonly used site that has statistics for win-rates, champ match-ups etc, you can see that Quinn has the highest win-rate in the game

The fact that you have 1500 games played as quinn and only got to gold is quite unfortunate.
And finally if you look at this screenshot you can clearly tell its a bronze player who abused the strongest champ in the game at the time to get to gold and is swiftly on his way back down
