Hi and welcome.
The league draw happening the third day but
it's not sure that there is the quality factor that put same q teams together.
Last season, I kept my team in low q as I was playing in the Cup, but in the league I had many strong teams.
My team had about 4* avg and 11 teams of the league had 5* teams (I 'm lv16). Only one had 4* players.
Some times you 're playing with friends, sometimes not.
It seems that it's different from server to server or there is a random factor too.
In the cup, it's strictly by the quality of the teams but I don't think it's the same in the league.
But still investigating.
