Here's my philosophy on it..
Let's compare to another League for example... National Hockey League (NHL).
This would be your LCS level of play.
Below that would be the American Hockey League (AHL) where farm teams are and where players are picked up to go to the NHL.
This would be your Ranked play.
Then you have your casuals, the "Beer Leagues".
This would be your Normal play.
So, why are you playing Ranked if you're not trying to make it to the LCS?
