First issue is docking; you can't queue at busy ports to dock so instead you have to spam docking permission which is incredibly frustrating. I can not fathom why a simple queue system isn't already in place.
I haven't had any docking requests denied/long queues for docking since before Gamma, so our experiences differ here.
Second issue is the whole mission/bounty hunter/combat location system. It's a mess. It's totally random.
I agree with you on this point, being a bounty hunter myself, but not to the degree you show here. 3 hours to kill 3 pirates? You're doing it wrong. That's definitely not the game's fault.
The third issue is a how this game practically forces you to become a pirate.
Except it doesn't, and if you think trading or bounty hunting aren't viable, again, you are doing it wrong. I've made millions off bounty hunting and continue to do so. I make over 300k in 30 minutes easily. The game needs serious improvements in certain areas, but these issues are on your end. You're blaming the game for your own shortcomings here.
Trading is terrible. It's completely broken with the current tools available to you and the only profits you make are in trading on courier missions for a bit of pocket money(1k CR is abysmal for 10minutes travelling and docking from one system to another).
...what. Believing that freaking courier missions are more profitable than trading proves you're doing something terribly wrong.
Bounty hunting blows as mentioned in my second point about how utterly random and low the chances are you can come across a bounty/pirate.
Random and low chances? I sit in supercruise in a system for five minutes and I'll see a wanted Asp, Python, or Anaconda show up worth 20k in bounties minimum. Sweet moses, son, what are you doing?!
So much is just poorly implemented. I want to like this game, I want to enjoy it and I really want to sink my teeth into it but I can't do that right now because 90% of what you do is a complete and utter waste of time with absolutely no payoff.
There are most certainly things that should be implemented much better, for sure. You're right about that, the hunting missions and some assassination missions being among them. However, 90% of what I do in the game makes me money, full stop, and the other 10% is me just flying around and donating goods to faction for rep boosts. I could write a book on how to "properly" play the game, but I can't understand how you're having these issues. None of this is difficult to figure out or execute, but perhaps someone else later in the thread will feel generous and go step-by-step of how to perform the basics.
