So in match making, I can never find any teams for the mission I need to unlock new ones. I'm always partnered alone with the 3 Cortez brothers.
I know it's not because I cant find any matches at all because this would happen 2 minutes into a quick play search.
I have no problems finding matches for these missions....well, some of them, i think people genuinely hate destroyer of worlds, after i've cleared them at least once, either with a premade or by myself.
Soloing aneska with hive wasn't fun.
Not entirely sure if this is a bug with MM or an intentional feature.
