Modding bounty hunters?

Depends on the lead but with Bossk protection and health and typical mods for attackers. At least crit damage triangle on all attackers.

Embo's special does (a lot of) damage based on his max protection, so I think protection primary on his cross is better than offense. Also his secondary mod set should be health to make the most of his foresight and zeta if you have it. He, Dengar and Greedo should be modded more for crit chance because of their abilities.

Only Boba lead really requires special modding. Max potency.

CD/CC sets with protection circles, cd triangles, protection or potency crosses and speed arrows for the attackers. Same for Bossk except health sets. Dengar and Cad could also sub in speed for CD sets, since they rely more on debuffs than raw damage.
