When it comes to scum you don't get more symmetry than Drea with R4-B11.
Kavil with Argo mech makes for better blaster turret shots, or essentially anybody using blaster turret.
I thought this would be great. Then I tried it; 1 and 2 straight for only green maneuvers didn't work out too swell.
I like Hobbie and R3-A2 they're a natural fit.
Bigg's with R2-F2 and Experimental Interface is nice. Played against a list that had that and tactical jammer. Took forever to kill Biggs.
You are missing the point of R4-B11 on Drea. Drea doesn't stop getting target locks by adding stress. If you work it correctly you get infinite target locks to spend.
You're right. I missed that little fact of stacking multiple stresses.
