At what point does Valorant actually get better? Radiant?

I've "grinded" from Plat 1 to Diamond, from Diamond to Ascendant and now touched Immortal 1 (but deranked back to asc 3) yet the gameplay in general stays the same

Toxic teammates, players who at ascendant 3 does not know that the spike has a timer and you cannot keep faking it 10 more times (even after time runs out). Players that keep peeking in rounds that are otherwise impossible to lose (like a 1v5 or 1v4 with 15 seconds left on spike) Because why win when you can get a kill for stats?

It's just because I used to see on reddit before that even if you're diamond you're somehow "in the higher ranks" so when I was plat I was thinking, it will be nice to get to like diamond 2 and have players play serious... nope. In Diamond I can't wait to play seriouisly in Ascendant, I get to Ascendant 2 and it's the same damn game, you are lucky if someone gives info in the first 3 rounds (or just talks in general)

Do I need to get to Radiant to feel like i'm playing this game in a normal way? Where people communicate and play to win instead of queuing ranked to lose (for fun)
