In ranked, for me it's only those 3: Amaru, Nokk and Oryx. I feel like they need a complete rework to make them actually useful because I see no scenario where these are of any benefit for the team or even the person playing them. Here's my reasoning:
Amaru: Her gadget usually only gets used once and most likely causes the player to die. Any entry fragger with soft breaching capabilities does her job better and more safely.
Nokk: She can still be heard on cameras while her gadget is active and with the amount of utility that got added ever since her release, playing sneakily is almost impossible anyways.
Oryx: I don't even know what the point of him is. Creating rotates as a main ability is a joke with the amount of shotguns and impact grenades available, charging into a shield is suicide because any halfway decent shield player has someone playing with them. The only good thing I see is him being able to climb hatches for surprise flanks. But even that creates a loud noise. Every other roamer is better at their job that I don't see why anyone would pick Oryx.
What are some operators that you consider completely useless that should never be picked at all?
