Just wondering why everything is messed up?

Anyone else notice that ranked system is just super messed up? I keep getting new players/bronze players in my ranked solo games (im gold) and diamond players in my flex games. I have yet to enjoy a good game of ranked in leagues for some time since the new season dropped. All I seem to come across is either my team dominating or the enemy team dominating. Personally I like the challenging games not the ones where you know who is going to win in the first 10 min. Also when is there going to be a buff on adc? Everything seems to kill adc's so much quicker this season, makes adc not playable. Please just make league great again!
