Sorry, but I can't really follow your argument. If I get you right you are afraid that solo players with NPC crew would have it easier than coop players with player crew?
What if without NPCs, coop players have it easier than solo players?
Why does it even matter?
For me NPC crew is mostly about not sitting next to an empty seat, not so much about the meta. The meta is the last argument that should be taken into consideration when designing game features and then balanced accordingly.
Also, it's pretty clear that we will get space legs at some point. I like the idea of walking around in my ship while my copilot flies it.
'But automatisation would mean I could just go AFK while the computer does all the "work"!'
Not if it's designed in a way that still requires your presence, for example calculating jump ranges and navigation.
'But this would mean that crew is mandatory for some ships'
Yes, why not? Didn't play the old games, but AFAIK it has always been like that.
No, that's not at all what I was getting at buddy....
It's nothing about advantage, and all about which becomes the more enjoyable way to experience the game.
Either NPC crew will be fleshed out to the point that it's fun and engaging and there is no reason to play the game any other way, which completely changes the dynamics of how ED works and makes about half of the ships completely undesirable without a full re-design, or it'll be broken beyond repair. Doesn't help that most of those ships that would be getting the shaft have already gotten it and are some of the most unpopular ships to date.
So you cut ship variety in half right off the bat or spend years retooling them. Sounds productive, right?
Or scenario B is that NPC crew are so janky and gimped that players would rather never experience it again after their first 30 minutes, in which case what was the point?
I want, so gimme? Is that the logic we're following now?
You're not going to find a middle ground. There is no way to implement NPC multicrew CORRECTLY without making it a mandatory part of the game. Your only other option, to screw it up, isn't fun, so which do you choose?
