I too have seen a much improved Crucible experience since I've had access to SBMM. I'm an average player, but I do pretty well in Iron Banner. Believe it or not, I'm in the top 1.3% of players with an ELO of 1966 in that mode. Dumb luck. lol I also have a good time in Survival Freelance. This is the best PvP has worked for me since Forsaken launched. CBMM can drop dead for all I care. It sucks in Destiny. I still get lag and horrible matchups. It has no benefit for me.
