First order SF tie fighter

I"d drop boba to reinforce, fives has irresistible target lock. That's why. But i'm not a huge fan of umbaran either, because he spreads tm to enemy like a wildfire.
Also if you have sf tie but dont have reaper and vader, maybe you should use sf tie in the front lineup and unmask as reinforcement, because it's better to start the battle with as much target locks as possible
