Maeve struggles against groups of enemies, so stick close to your team, especially if you are a support, because you can pressure her either fight, where she will most likely lose, or to flee.
Not much you can do against Inara. If you're set on killing her, buy Bulldozer 3 and help your teammates tear down her deployables. Shadow Step her ult if she tries to hit you with it. Don't go in alone, because you don't have the power to finish it.
