Last month, in the 15-20 ranks, the quality of decks was HIGH, and getting wins was tough. Lots of decks had multiple legendaries at these ranks. There did not seem to be many other "shitty players" playing.
I put together a legendary filled deck, and did fairly poorly with it making it only as high as rank 13. A shitty player with legendaries is what I was called on these forums.
In disgust, I went back to no legendary - no epic decks, where my 6 drops are like the 6-7 mob with no other characteristics. All my decks have had all legendaries and epics stripped from them and reformed.
And in the 18-20 range I am basically playing a nice mix of beginner type decks, with games that are competitive AFTER turn 5, with very few legendaries or epics anywhere to be seen. I am having fun
People are respectful, saying Good Game after they lose, and are mostly not using Good Game as a "Look how good I am" display of insecurity when they win. People play promptly, and have also been creative in finding ways to gain advantages. I win some, lose some, and am thoroughly enjoying myself.
I hope this trend continues! And while I am at it I propose a minimum rank of 15 for any deck with a legendary in it.
