This is the premiere pilot for the ARC-170 for many reasons. Pilot skill is important, but also her pilot ability can crank out damage.
Using her target locks to increase the damage of her attacks, Norra can potentially generate a 5-dice attack at range 1 of the target. The target lock can also be spent defending, slightly increasing her survivability.
There are a tonne of potent combinations available. Consider Kyle Katarn for focus tokens, Push the Limit for dual actions and a stress token to activate Kyle.
A very tanky combination, however, is R2-D2 with C-3PO in the backseat.
