Caliber
Caliber is about roles more than raw rushing. Each operator brings a job to the squad.
Match the Operator to the Task
Pick support when the team needs sustain. Pick assault when the push needs pressure.
Keep this resource open when you compare operator jobs before queueing.
Use Utility Before Contact
Good utility makes the fight easier before anyone goes down. You can review additional game information when planning PvE routes or 5v5 holds.
A slow revive is better than a failed rescue in the open.
