Bossk or aurra lead for chewie

I was wondering the same thing.. sitting on a zeta trying to decide

Bossk for sure. Survivability is key

Aurra is a nice lead because all bh are attackers, except Cad and Bossk. But I'm not sure her leader can handle, mainly because after the first stealth end you need to actually defeat someone to get benefits from contract.

If you don't really want to invest heavily and put zetas on bh squads, I would recommend to save this zeta and use if needed. But as Bossk is safer, I'm more inclined to say that this is the zeta you want for this event.
