In Any match you will find Parties of 5 players all with max level legacy WITH a star are coming and all are in same team. Being in a party should not mean we should be in the same team. It just means we want to play with THAT player who is our party.
So I have two suggestions:
1. Either all party members should be shuffled and teams should be made like there was no party
2.Parties should not be of more than 3 players.
I think the solution is 1, But whatever it is I dont want my opposing team with all 75 with star unless My team is the same
