Stormleague as Team with Master/Diamond players

How do you wanna improve as a team if you are all in the diamond/master league but can’t play together in stormleague cuz of the restriction with master players. Only playing unranked draft or looking constantly for scrims isn’t fun either.

We need to make alot of smurfs to play together which should’nt be the solution cuz it destroys the matchmaking even more.
