I didn't downvote any comments. I thought you had a very positive outlook. My apologies if I came across more negatively than I'd intended.
I do think that it's super frustrating to play against some of the best players in ranked play before you even hit max level. And I don't believe that's an unreasonable stance to take. You don't learn much when you face an opponent and get face-rolled just like you don't learn much when you face an opponent who is significantly inferior to you. You learn the most when you go against someone at your own level, or slightly higher.
One of my matches last night, I ended up being the only player on my team not gold or higher (with, I think, our top laner being diamond). And, even though their adc quit early on, (their only non-gold+ player if I had to guess) I spent most of the match unintentionally feeding and overall just being fairly miserable. We very nearly lost (which I'm certain must have been my fault, despite my best efforts) despite having a numbers advantage.
I found the experience far less than enjoyable and I can't help but think a lot of people would have been in the exact same boat.
