Smoothie: Incompetent and Useless despite being a commander
Compote: Hyped up with the other veterans and yet we didn't see anything from her
Yamato: A mentally ill women who thinks she is Oden and has no unique personality
Rebecca: Another Nami clone who is known for crying a lot and isn't able to fight back
Robin: Has been getting less focus when the Water 7 Saga ended
Boa: Just another Luffy fan girl
For anyone who thinks that only Big Mom is getting treated badly it isn't, the same thing also happens with plenty of other female characters.
