Right now is FW missions are often abused by awoxers who kill friendly militia members. One loses faction standings by friendly kill but able to fix it in like 20-30 minutes by doing few L1/L2 missions to get next rank and regain statndings.
I think, it is good idea to decrease ranking speed with FW missions by factor of 10-20 (right now it is like 3-4 L1 missions gives you next rank at lower ranks which is ridiculous).
