A lot Less Players are willing to get to Masters and Challengers in Season 7

Season 7 has began for around half a year, but there aren't even 200 challengers in Flex 5v5, and Solo Q players only need 200 + LP to get to challengers. Due to the new system of masters and challengers, players need 1 game per day to keep their position on the ladder. This is really unusual, Players need to be in queue for around 10 minutes - 60 minutes in Challenger flex 5v5, and 1 game took a long time too. Sometimes, it may even remake. People are so exhausted after a short period of time after getting to challenger unless they are putting their whole life into the game. I think this problem need to be solved
