WHAT THE NUMBERS SAY

This is the role's baseline play, winning more often than not while producing far more metal than it loses or destroys, showing its value is team eco, not frontline damage.

  • + Team won most games despite near-zero kills, showing its value is enabling teammates.
  • + Metal output snowballs hugely, 4716 by 5:00 to 24757 by 15:00.
  • − Own metal lost stays low but creeps up to 464 by 15:00, some exposure late.
  • − Nearly all labs get reclaimed, so mistimed reclaim could starve early BP.
