There's a separate thread for this topic but guess I'll respond here as well. I see no issue with the current way crew works, it's very abstracted but so is the rest of the game. "It's just a resource", so are supplies, which again don't really make sense. Like what do supplies even do, feed the crew, nah there's food already. You maintain your ships with crew, ok sure but supplies is a weird name for it. Your ships get damages, use supplies (even though metals exist). CR recovery is also somehow tied with supplies. So basically they're the duct tape of the Persean sector.
Marines don't need Heavy armaments.
Having drugs or any sort of commodity in your fleet doesn't have any effect.
My point is, if you start to think about things logically, suddenly you can take apart the whole game. And let me remind the fine folks here that the game leans more on the arcade side than the sim side.
If Alex decides to do anything with the way crew works, I sincerely hope it's not something annoying and demanding.
