I too played many more normals than ranked matches, but I don't really mind.
I'd imagine ranked flex allowed them to remove normals. Many people treat Flex like a normals queue anyways (and it literally replaced normals in some regions).
I'd also guess that many players complained about normal matches skewing their review. Like having their KDA destroyed by a bunch of games on champions they don't know. Ranked is where you're evaluated, so it sort of makes sense. I'm glad to see a few highlights from the ranked season, since I stopped playing ranked months ago. It's particularly nice to go back and see the game I carried 15/1/27, be told I killed a baron at 20:02 (would love to know what game that was), and to see that despite being gold all my stats for top lane are superior to diamond players and similar to Master, and for mid are similar to Diamond players (which honestly makes some sense, since my normal MMR is in the top 4% and has been as high as top 2%, and I just don't play much ranked to climb).
Also nice to see that I lost to Poppy a whopping 87.5% of the time - really justifies that she was my go-to ban for the majority of the season (and only really got through when I didn't have a ban) (my go-to J4 top just gets crushed by her).
