Destiny 2 - I don't have time to explain Bungie's MMO shooter 2.0

Good idea to let a group of 4/6 solo players face a group of 4/6 solo players instead of what is more often the case, 4/6 solo players facing 1 or 2 fireteams consisting of 2-6 members who then proceed (more often than not) to curbstomp them in a totally unbalanced match, in terms of “ELO” rating, chance of success and ‘team’ composition?

Yes, I think so.
