Expertise is a good investment in general if you're rolling 3 or more dice. For 4 dice the free focus effect takes you from an average of 2 hits to 3, and you still have your action available for locking, barrel-rolling/boosting, etc. Just avoid stress when possible (so be wary of trying to combine it with Experimental Interface or Glitterstim etc).

There's an argument to be made for Predator + focus token, which provides nice odds even if you're facing stress, and is a point cheaper. But unless you're facing heavy stress, IMO Expertise + Lock is even better, granting you an average of 3.75 damage, very close to the max. (I'm using this calculator, btw)

What ship do you want to equip with Expertise?
