blitz < rapid in leagues ??
Think about the time per game. The average time of a Rapid game will be longer than a Blitz game. Therefore, Rapid games should give more points to compensate for the time commitment.
I'm actually pretty sure it's easier to get trophies in most blitz, especially 3|0 or 3|2. You can have a lower win percentage in the same time frame of a rapid game, and more games you are more likely to get that win percentage.
I play 5/5 blitz so I might as well play 10 min rapid and It's easier to win one 10 minute game than 5 bullet games and less stressful over time.
People cheating at 1600 rapid probably aren’t good at cheating. So by Occam’s razor your opponents are probably not cheating
