Honestly a better baseline would be too look at the number of global kills vs the number of global deaths in crucible. This would actually be the global kd that would function as the base line for if a 1.0 kd is above average or not. by global i mean add up all the kills and deaths of every player in destiny in the crucilbe then use that as the global kdr. I think this kdr would probably be closer to the 1.0 kd average that people give.
