I feel your pain brother. Tbh I think Bungie has messed around with matchmaking ... it seems a little broken to me since to patch; at least in my experience. It takes literally ages to find me a match, a lot of players will have red bars, and I usually seem to be matched with players who have a higher skill level than me; so much so that my k/d has dropped from 1.79 to 1.69 in the past few days!
