I currently run a bossk lead bh squad with boba, jango, and dengar who are all gear 13 and between relic 2-4 with a gear 12 greedo. I want to replace greedo with either aurra sing or embo but can't decide which of the 2 are best. They both need work as neither are 7 star yet but both candidates seem to possess strong skills that would benefit my squad nicely. Aurra can topple raid bosses and gains stealth frequently while embo can remove buffs on basic cant be critically hit and recovers a significant amount of protection. I know embo a a great leader for bh squads but I'm not sure which one to go with.
