Moff VERY low damage, needs a re-work? Is he for defense only?

He's excellent for nerf-ing the other team's offense in GW, Arena, etc. AoE debuffs work near-constantly under Palpatine or with really high potency on his own.

His Zeta unique boosts his Potency to ridiculous levels when combined with Palpatine/Vader or other debuffers. Which then increases the offense of Ultimate Firepower even further. I've wiped out multiple attackers from full health with it when timed right.
