This exists for LS so as to stop dumbasses from going gangster next to you when you aren't paying attention, killing you and then moving on. I agree that it's useless in LV since everyone fights with everyone but at the same time it's a waste of time to add this, most of the time you'll do /gangster once and then continue on playing.
Keeping it in LV is useless to be honest. I know 8 seconds are few time. But imagine I came from LS for turfing with my group mates but they told me to assign as gangster but once I assigned as gangster another group attacked us and they killed me just because I am restricted. And in LV it is easy just by throwing grenade and rpg will kill victim. It happened to me today when we turfed in lv. That's why I thought about suggesting removal to it. Just a simple edition will make some balance and reduce inconvenience.
What if you become a gangster before going to help your group instead of becoming a gangster only when you are next to the enemy? friend we are talking about only 8 seconds which nobody bothers, only you from what I can see, that you do not know how to take advantage of time is no longer our problem
