Don't blame you at all. And SBMM doesn't even work properly: my connections are still crap (got hate mail the other day for red barring but it's not like I chose to red bar) but games are still lopsided where the other day I went 4.0 k/d with 16 kills and 4 deaths while red bar, and I was third place in my team. I don't think anyone on the opposing team went positive. Not isolated case either. I prefer CBMM so both my deaths and kills feel justified, but you would think that once a lobby is established that the game would balance out the teams with roughly the same skill level players on each team, not attack all the good players on one team.
