Axis by axis

Marathon leans harder on execution: Gunfights against other crews reward raw aim heavily
Reads6 vs 7
Marathon leans harder on reads: Predicting human crews' rotations and ambushes is constant
Variance6 vs 5
ARC Raiders leans harder on variance: Loot spawns and unknown player positions
Optimization5 vs 5
