That's pretty impressive. Especially considering it didn't look like you were playing with your Clan either (unless your friends aren't all in the same clan?). I generally try to stick with my fireteam for PvP, since Destiny 2 has a knack for matching solo-queue players up against stacked fireteams :/ My friend introduced me to Guilded recently for coordinating fireteams for PvP and Raids and stuff, since the Bungie recruitment site isn't great if you plan on ever playing with any of the same people again. I highly recommend it.
