I'm not really that hyped up about the drone for Cassie either. But hopefully they show her with it in story mode and give her a reason to have it like you suggested.I keep thinking about why did they give a drone to a character that already had enough versatility rather than giving it to the tech-nerd Jaquie that many think is bland and needs more personality on her moveset.
There is a move where Cassie charges her arm with the drone to release energy.
I hope the drone's purpose is to help her control, contain and manage her green energy powers, that would make sense and justify the use of the bot rather than it only being there because it's cute.
It does come with some cool moves though, so it's not that bad.
