Unskilled players are even more detrimental to the team in Destiny than in other shooters. Having a really terrible KDR does actually matter in Destiny, because the more you die, the more you feed the enemy teams' Supers. I've been in a number of matches where, not only did half my team not understand how to properly fire their weapons, but the enemy had Supers ready going into practically every fight. Feeding is now a legitimate obstacle in Destiny.
