that is a problem with matchmaking dynamics in every single game. there is no way to account for all of it. I have 100 PvP quick play wins and I have had some frustrating matches. that has nothing to do with the mechanics of destiny at all. if you know you can't win a fight by yourself, don't go into it. it is entirely possible for you to go through most PvP ecounters with your full squad, let alone at least one buddy next to you. If you're going 1 vs. everything then no wonder you aren't winning.
