In theory SBMM is a good idea, but, it needs good execution. There needs to be more weight on a players performance rather than their elo. This will fix not only account boosting but also help good players get to where they belong. Also currently pushing in PvP is impossbile without flawless team co-ordination. This is to say nothing about the current scout rifle corner camping combo. This is very noncondusive to a healty PvP meta. Please reach out to me if you have further questions. @bungie
