ID is more important, but out in the Omicron's freelancers and mercs etc. aren't the most welcome. Plus as far as we know you could be doing solo jobs for the navy so we wouldn't want you around.
In all honesty, whether I fly as lawful or unlawful, I now turn a blind eye to Freelancers and Mercs. Sure, I'll acknowledge their presence if they hail me, or ask for assistance from an allied faction. Otherwise, they're just way too unpredictable to get near to. Most of them I see have their ship/IFF/ID/Weapon combos so screwed up I have to stop what I'm doing just so I can give it an appropriate facepalm.
Long story short, Freelancer ID = Freelancer IFF. I cannot stress how much easier it will make your life.
Tycho, guess who? *Waves from his character C.Retriever*
Anyways....
Since you were telling me before that your rep has so many people fully friendly with you, you can either do one of two things without having to blow all of your money on /droprep.
Either A) Fail about five missions for each faction you are fully friendly with, doing your affiliated faction last, and dropping missions for the affiliated faction to neutral instead of just "almost fully friendly."
Or B) Transfer anything of value on your current character over to a friend's, then delete and remake your character to get the "clean slate" that all new characters have. Then, head over to Corondo to double bribe the Freelancers on the station they own there. After that, get all the stuff you gave to your friend back on the new, Freelancer IFF'd character.
To do a double bribe: Keep logging out and back in on the station until two different people in the bar offer the same exact bribe (Freelancers in this case). When this happens, buy them both, and you will automatically be "fully friendly" to the faction (Again, Freelancers in this case). Viola: Freelancer IFF. Make sure you don't kill Bounty Hunter NPC's, otherwise Freelancer's rep will drop. Finally! No more controversial killings!
