Ok started practicing already. Got a much more agile ship after that mission anyway. A few things ive found:
1) I find it easier to dodge objects whilst shooting in the outside view rather than in-cockpit view.
2) Setting hotkeys for CRUISE, GOTO, DOCK and NEXT TARGET seriously help in escaping whilst having MOUSE LOOK on
Ive been practicing running in circles and strafing whilst targetting a jump point, activating cruise and then docking when im almost inside the green light ring.
3) Engine off seems useful, but hard to master. I keep instinctively pressing the up and down keys immediately after. Bad habits
4) One technique that works is instead of doggedly following one target, I use a mouse button set for rear view to glance behind me when i recieve damage, i then hit reverse thrusters and target nearest whilst strafing sideways. So far ive had 90% success in getting the bugger dead center. My original target is usually 1k away at this point and certainly not on my ass.
Im now doing difficulty 8 missions in my sleep. Im even playing just to get my skills up for the next story mission. i.e. sometimes i dont fire a shot for a few mins, or ill go into debris fields and just play hide and seek. Or my favourite is now rodeo
I try to get on the enemies back and see how long I can stay there without him shaking me off. I usually do this last enemy in a pack.
Perhaps when i finally feel up to the next real story mission I may not be as frustrated
