This is basically a continuation of a thread started in the beta forum: https://community.fantasyflightgames.com/topic/70643-droid-system-fail/
I'll repeat my post here, because I fear no one's reading the beta forum anymore:
Having just finished reading all three Core Rulebooks and finishing my lists of all available species, career, and power choices, one thing immediately stood out: Droids suck. Like hard.
While I don't consider myself a min-maxer I really couldn't bring myself to ever consider playing a droid.
See, I get what FFG was trying to do, creating them as a species that was inferior to a biological species but with a potential to be superior in a very narrow specialization.
The problem is, they failed to do even that. No matter which other species you choose, you'll end up with a better specialist than when you try to do the same thing with a droid.
The balancing is just off.
For anyone not believing it, here's a challenge: Create a droid character that is actually better at something than a character with any one other species!
Imho, the final nail in the droid's coffin (or whatever else it is that they're disposed of in) is their inability to ever become Force Sensitive.
There definitely needs to be _something_ that makes them actually be good at something. Implants would be an obvious way to go. This is just screaming for a dedicated source book.
