At the very moment you won't earn much credits by doing combat missions or PvP (except if you're some sort of ace pilot).
As far as I figured, Elite always was very much about trading, that includes finding the right routes to make profit. That did not change much I think. So my question to you is: if you get "ganked" in a conflict zone... and you get a repeat performance every time you go there: why in all hell do you keep doing it in order to make credits?
If I run my head against a wall and come to the conclusion it's not a very pleasant experience, I try other options. Be it a helmet or just using the door that is one meter to the right
You play a game that is -as a big part- about trading. You want to earn money to afford your next ship. Why would you repeat going to a combat zone where you get your butt handed to you over and over again?
As this is still a beta, things are about to change, and I bet it will include increased payment for combat missions, bounty hunting or whatever else comes to mind. Balancing is surely one of the most challenging parts in game development. Give the devs time...
And maybe calm down before posting. Rage posts like yours are not going to get much help from other players (though I must admit that this forum has got loads of helpful guys, and they mostly are really polite and help newbies whenever they can).
I do hope you get the hang of the game and begin to enjoy it as so many others here do.
I know I do, eventhough I am not old enough to be a fan of the first hour of the Elite universe.
