I'm going to go against the flock here and just point out something...
You started off as a bounty hunter and then moved to trading. That's the whole point.
What if players don't want to trade?
Look, I can understand ships like the anaconda being worth what it is, and that's fine. It's a massive ship.
But the Vulture? That ship is literally not worth it. I played a lot with it in beta, and it doesn't scale well, and is no where as near as good as the ASP or even the cobra. So why is it so expensive? It doesn't bring anything new, or anything special other than a quick turn rate. You can combat in warzones well, but proper bounty hunting it doesn't do well at, trading with it is pointless with it's limited jump range and cargo space, same goes for mining.
Again, high cost ships are not a problem. The problem is gating out all this new content to traders only. The Vulture specifically is too over priced for what it is actually worth. And the biggest issue is basically players are being forced to trade if they want to experience a new ship, even if that ship is just a sidewinder on steroids.
The game is about doing what you want, players shouldn't have to go down the trading route if they want to experience new content. But OP, as you said, you started as a bounty hunter and are now trading. Because although you might not agree, you are effectively being forced to do that if you wanted one of the new ships.
The vulture and FDL are combat role ships. To keep up the maintanence cost of the ship, you will have to do trading in between combat.
Any ship should be able to cover it's own upkeep by using it for it's role. The T6/T7/T9 for example can by trading with them. The cobra can by fighting with it. The sidewinder is effectively free in it's own right. The Eagle is small so upkeep is minimal. The anaconda excels at a lot, even trading, so it covers it's own. The ASP is a jack of all trades, and can also cover it's own.
But the Vulture? It cannot. It's a combat role ship, with little firepower, low shields/ armour and can turn quickly. It cannot keep itself afloat with you being forced to trade in another ship in order to do so.
The Vulture has broken the balance here. If it had a huge amount of cargo and a large jump range, then it could be used as a trading ship, thus being able to keep it's own upkeep. But as it stands, it, along with the FDL, are the only 2 ships in the game that cannot.
