SBMM isn't the problem. It's the gross P2P connections that make this crucible unplayable most of the time. Shooting someone that blinks frame to frame only to not take damage until after they kill you is not fun nor fair in any way. If everyone who played destiny all had local connections to each other then no one would be complaining about SBMM because there wouldn't be any lag to blame lack of skill on. You would just have to git gud. Unfortunately that's not how it is. Far from it.
