In close range, depending on their timing of popping their Magic Marks on you, Moji can deal up to 1000 damage per second. Never give her a chance to flank and make sure to focus her down after she pops her Magic Barrier and scampers away.
Just pick something else. Maeve's mobility combined with her Double Jump and small hitbox makes it merely possible to land a shot on her, while she can burst you down in a few nanoseconds. Simply avoid her.
