[quote]no... they don't it is based on overall team ELO... I have been in fireteams similar to the OP and taken lead and it didn't change anything. All but be in the group were 1.0+ K/D me being sub 1.0 and still had a hard time getting 3-4 kills a match.[/quote] Why would bungie base the team composition from a third party stat? If anything they base it off K/D KA/D Combat Rating
