I would have thought that the anarchy systems would have a much shorter no fire zone than a well protected imperial system for instance.
If this IS the case, then I am sure that the fun will still be there, just a little further out!
I think anarchy systems SHOULD be rougher (and I am a generally trader/co op player). The game needs places that are a proving ground for those like minded! Likewise I think that the aligned systems should be much harder to pirate in than anarchy (when it all comes together).
Don't dumb down the anarchy systems, I do not have to visit them if I don't want to get involved, and if I do go to try to run the gauntlet, I know what I am letting myself in for!
