Out of sheer curiosity for those who regularly play Rocket League, have you noticed a difference in your rank or the ability of players in your rank this year?
I started this current competitive season by finally breaking into Diamond 1 after three seasons stuck in Platinum, but as lockdown commenced and (I assume) more people had time to play more regularly, I found that my rank would plummet. I'm now barely holding on to Plat 1, but feel the quality of the people I'm playing against is almost the same as when I was fairly comfortably maintaining Diamond.
I did take a few weeks away from the game due to the frustration of losing constantly, but even as I've returned I'm finding I'm losing way more than winning - even in casual.
I hadn't played it in a long while, but I tried it out again last month and found the matchmaking pretty poor.
Half of my matches were ok, two teams of newbies playing ball, but the other half my team were stacked against teams of 3 advanced players (with the same code in their names) scoring tons of goals while we barely got to hit the ball. I looked up some youtube videos on how to play better, and that was actually what made me realise how unfair the matches were - I was able to recognise the moves I was trying to learn being used frequently by the enemy team but not my own.
In the end I just quit because I have a lot of other games to play and my friends don't own the game either.
So I've no idea about the higher ranks where you are, but I can tell you beginner's matchmaking was questionable.
