I'm now always checking the roster and immediately backing out if the opponents have a fireteam.
Saves me a boring mercy.
And maybe if more ppl follow this rule, Bungie has to fix their matchmaking.
I always checked the roster before every match in D1. I often backed out if I saw a large fireteam -- or multiple fireteams, which usually were put on the enemy side, instead of being placed on my team. Unfortunately, nothing ever changed. Bungie either does not care, or they are clueless.
In D2 I have checked the roster, but I have not bothered to back out much because whatever we do this week means nothing in the long run. It is a good time to experiment before the game is released in September.
