For me, some Phoenix toons are more viable under another lead than Hera. ie Ezra in a Jedi team. For sure some other toons can fit in a variety of teams.
Zeb: can Daze and if already Dazed then Stun target. Also provides Retirbution for him and a target ally.
Team: EP(L), DT, Krennic, ShT, Zeb. DT and Maul can Daze. DT and Zeb will stun at second shot. Krennic can stagger, same thing here with Zeb. He can give Retribution to EP, can be fun to have a lot of shock toons.
Sabine: can Expose and Stagger.
Team: zFinn, RT, Poe, R2, Sabine.
