ranked falloff

i'm the biggest primmie glazer ever but it feels like a lot of ranked players have fallen off from their insane ranked dominance eras. primmie used to have near perfect stats in ranked but he doesn't have those same stats anymore (although they are still very good stats rn). i know they have a lot more scrims and less time to play ranked also probably burnout or too lazy to try in rank, but is there anything other than that? i feel like whenever these mechanically cracked players learn team play that little ranked spark in them dies out and they stop going as crazy as before
