UP TO 30 POINTS
Role performance
How well the operator solves the main job their squad slot is there to do.
EDITORIAL STANDARD / V1
How we score.
Every profile publishes its component scores, reasoning, and separately assessed training and acquisition advice.
Power Index / 100 points
The index adds five editorial scores. It assesses practical Global performance in story, events and general challenge content, assuming a complete role-defining build for that operator. Promotions, skills and standard modules count when they materially affect the role. Mode-exclusive modules, special relics, potential upgrades, and acquisition cost are outside the baseline.
UP TO 25 POINTS
Stage coverage
How often that job matters across story, event and challenge maps.
UP TO 20 POINTS
Reliability
How reliably the operator delivers despite timing, tile and enemy constraints.
UP TO 15 POINTS
Distinct utility
Useful mechanics or combinations that would otherwise take another slot.
UP TO 10 POINTS
Team fit
How easily the operator fits common squads and deployment orders.
Use each dimension’s maximum for standout performance in its category. Around three-quarters indicates strong results with meaningful constraints. Around half indicates a narrow or frequently replaceable contribution. A low score signals that the operator rarely delivers that dimension. These are editorial estimates. Small differences between totals have limited significance.
Three independent evaluations
Upgrade value
What you gain from the next recommended stopping point relative to the resources it takes. Low-cost E1 investments can score highly.
Acquisition priority
How urgently a developing roster should fill this operator’s role. Limited availability and overlap with easier options affect the advice.
Training difficulty
Combined promotion burden and how much practice it takes to use the recommended kit. This label describes effort.
