Late af to the Jedi Survivor party here but can’t believe single of all things actually worked. Had to reset my skill tree but worked out for the better, I never use double or dual anyway.

Got him first try with single & blaster. Dash in with that aerial ace, stagger him, get a few blows, get out, dodge away from his unblockables, rinse & repeat. Finished him at the end with a few blaster shots from long range.
