Are there any mods allow you to have more crew members without the Ship Command skill?
Quick rant incoming...
This skill always drove me nuts in-game because I don't think the number of ship crew members should be locked behind a Master tier list, of all things. The player should be able to hire the max number of crew members capped by the crew stations of installed habs because that would make more sense. The bigger the ship, the bigger the crew required to keep it operational.
That being said, I think Ship Command would be more useful if it related to how effective the player is as a ship captain i.e. Rank 1 - you're considered an acting captain. Your crew is happy to have work but will only do the bare/standard minimum. So it's like they will provide the buff related to their skill but only at 30% max. This increases as you rank up and by Rank 4, it will be the full skill buff and maybe a bonus or something.
I think that would be a good incentive to level up the skill because it incentivizes the player to invest in their experience as captain. It's also an evolution of the relationship between a crew and their captain.
Anyway - if you've made it to this point thank you for reading my rant. I'm not sure if such a mod exists (see above) but would be happy to download if there is any. TIA
