the white blip system was removed for various reasons the main one being.. There is no benefit from having all white blips, Criminals who "wont" evade as soon as they see blue can just assume that white is going to be a police man eventually after being rushed at a drug spot of approached while being suspected etc, And for those who are active to notice the white blips and the current script don't really match together with coloured jobs.(vice versa)
This doesn't mean blips will always be coloured again, How about we do something useful and make a decision based on the players thoughts?
We can either keep the blips white and have everyone on jobs pop up in chat as coloured or make the default job colour white and not be able to tell anyone apart unless found out in roleplay or by appearance(clothing)
Or we can go back to having coloured blips [Pink - Medic] [Red/darker red - fireman] [Blue/darker blue - Law] [yellow - Mechanic] [Green - Taxi Driver]
