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

Tarkin is all about potency. 30% is not enough. You want him to have potency coming out his ears. Keep leveling and gearing him up and he gets much better. Mine is level 85 gear 11, has 83% potency, and he’s effective in my arena team and in raids. He’s especially useful for taking down the enemy team’s turn meter in arena battles.
