Lag is why people are complaining about Skill based matchmaking. The current setup of matchmaking is putting players in matches based on skill instead of connectivity. It doesn't matter how good your internet service provider is, if you're being connected to someone across the world from you you're going to see a drop in connection and your game is going to be very poor. Bungie can't fix a player's internet but they can fix multiplayer to put players in matches based on connectivity so games run smoothly. This is why people should be complaining about Skill based matchmaking. However I agree completely with your post if the players are arguing against SBMM because they are being challenged against similar rated players rather than less good players. The whole point of competitive multiplayer is to fight against rivals of similar skill. Unless Bungie release a social playlist where you fight anyone of any skill, you need to deal with being beaten or losing your precious K/D.
