Expertise is like Predator in many ways, but a bit cheaper and more synergistic with Fire Control System and Target locks. Here's a squad highlighting its usefulness:
Horton Salm (38)
Twin Laser Turret
Engine Upgrade
Expertise
R2-D6
Biggs Darklighter (29)
R2-D2
Integrated Astromech
Sabine Wren (19)
Jyn Erso
Crack Shot
Sabine's Maserpiece
Captain Rex (14)
Total: 100 points.
Horton has a TLT that rerolls all blanks, then converts all focuses into hits without the use of any actions, leaving him free to boost to his heart's content. Sabine feeds focus tokens to Biggs while Rex pins down the heaviest hitter on the opposing team with Suppressive Fire.
Horton averages 2.8125 hits per shot, which is a spread of about 3, 3, 3, 3, 2. This is incredibly reliable, mid-level damage output. However, he's the only offensive power on the squad. How could I improve on that?
