The rest of my team will be Dengar, Zam, and Greedo for the detonators. I like Bossk because the heals his zeta gives when you throw those detonators out, but Boba Fett's turn meter on detonators seems valuable as well and I have a lot of really good potency mods to throw around.
I've got Bossk at g12, Boba, Greedo, 88, Dengar, and Cad Bane at g11, Zam at g10. Bossk is double zeta'd, the rest are full on omegas but no other zetas. I've been getting brutalized so far, but that could just be RNG. Any squad composition substitutes are welcome advice.
(Also, since this is a 12 day event, I'm not super worried--I feel like I'm close, so can always get at least one more gear level on some key character if needed.)
Ceterum censeo Patientia esse meliat.
