I wholeheartedly agree!!! The Fleet Carrier should be much more configurable. If you're an explorer, you should be able to modify it so that it focuses on that at the expense of other features, ie cargo space, ship carry capacity etc.
If you want to be a warlord, more firepower at the expense of jump range. Space trucker? Cargospace and jump range at the expense of weapons and ship storage. Make it modular. Make it so you can modify the carrier on a sliding scale, so you can specialize, min maxing, or generalize, or sonewhere in between.
Also there needs to be more reasons for pilots to seek out fleet carriers for various transactions.
Make FC owners able to hire engineers that can (given enough $$$ and mats) train to be able to fully engineer including experimentals.
Make crafting modules a thing. These crafted modules have the possibility of being tweaked to increase their base stats by up to 15% before engineering. (You could even use this as a mechanic to get players more involved with Odyssey play, requiring mats only found from Odyssey missions.)
And player crafted modules can be sold on a FC.
Allow players to sell engineering mats from their FC.
Allow FC owners to be able to restock ships with standard or premium ammo. (For a price... Hehehe)
Allow owners of FC's to offer missions to players for whatever they want. Want to overthrow a power? Offer crazy high paying missions to players willing to undermine the target power.
There is just SO MUCH untapped potential with FCs that needs to be addressed.
