It's part of internet MMO 101
Agree with that - no matter what online game you attend.
The existing system certainly blows and nothing since the Mobius incident seems to have fixed it. However, if you hold true to the concept of 'security' in the ED universe it makes more sense that High Sec systems are 'more dangerous' for PVP'ers per se as a result of heightened security responses, bigger / better armed and armoured ships etc. It might even make trying to infiltrate such systems a worthwhile economic or just plain 'fun' endeavour for a wing of dedicated pirates!! Would be good if security ships actually responded fast enough too!! Or if they were automatically in the instance the second you got interdicted would be better.
There's also the station docking and 'pay fines' thing the needs a bit of a tweak for WANTED status.
If they can, or will, rank award crew in multi-crew why not 'rank' pirating rewards too. If an Elite player kills a mostly harmless player ten the Elite player should actually LOSE money!! Likewise the other way around...
Don't know if you can do this dynamic with differing ships or load-outs - might be too complex a mathematical formula to standardise for use.
Then the 'anarchy', 'uncontrolled', 'rim' sectors would be where all the action was at! So kinda like the Wild West in space. Closer to the 'centre' of controversy l and security the harder it is to break the law - further away - the easier it is. The whole pirate / civilian dynamic still needs a tweak and it does look like its coming in 2.3.
