Next BH zeta

I am working hard on my BH and I have pretty much fun playing them especially with the new content / new events. Also I am tempted to try them in arena although I know they are not designed for this purpose.

As I have two zetas ready now I am wondering who of my BH should get them. The squad I intend to use: Bossk / Boba / Dengar / Embo / Greedo. Maybe Aurra would replace Greedo. The zetas I already have are:

Bossk (lead)

Boba

(Bossk is 7* + G12 meanwhile)

Following options and my thoughts on them:

Greedo: His unresistable stun is quite nice and helpful

Bossk (unique): Taunt re-gain is good, but only if weakest enemy has prot, so it depends > too weak for a zeta imo

Dengar: Kind of defensive zeta, increases his survivability (he is very often the last one standing anyway)

Embo: His unique is imo better than his leader ability, increases his survivability significantly.

Aurra: Her unique is good for raids (not my primary focus), her leader ability gives a boost to the attackers > 2 turns stealth > 30% offense up, thus maybe a good choice to put her in leader slot if considering arena squad

Now your thoughts / comments please.
