This right here proves how important SBMM really is to Bungie. They will tell you SBMM is minimally used in matchmaking, but as soon as you find a group of skilled blueberries to play with, and you actually win a match because the team is skilled, you are shuffled into new teams because you all had skill. But, if you are in a fireteam, then the matchmaking attempts to match you with other fireteams because your skill level, as a unit, is said to be increased. So, SBMM is going to be a permanent feature regardless of the bungie proclaimed matchmaking tweaks. Unless you are a trials of osniper fireteam, this will always be a problem. You are not aloud to win. If you do, bungie thinks there is a problem.
