Yesterday after a week pause I played a few gambit games to find out if the patch did change anything (of course it did not - quest spawn was never seen). But every game was against a 4 or 3 stack on the other side. My side was always solos. So you think to yourself: If there are that many stacks, why not put them against each other? Well, I know the answer. This is called the "friendship bonus" or "friendship endame". The moment you group up, Bungie basically hands you every win and reward. And ppl know that it is true. Why else would every Luna owner tell you "I did it solo" :)
