I am pretty sure I did not day sbmm would make me a better player, what I did say was it would allow me to play against players at or around my level and this would allow me (hopefully) to not be mercied quite as much and, as a consequence, I may be able to improve. Obviously no guarantees. Obviously there are issues with this idea, some of which have been pointed out to me, but there also seems to be issues with cbmm and as Bungie decided at the beginning to run this more peer to peer there will always be issues that cannot be overcome. However if you are satisfied that the current PvP system is working well and recruiting new players who are learning the system and just doing crucible because it's a really fun place to be and not because of the loot, weekly challenge or pinnacle gear makes them do it then hurrah!
