As a newbie myself with just over 24 hours of playing i've found out that being a gangster is terribly hard if you are on your own, and I didn't know about this feature so I agree.
If I may add that the fighting system as I see it right now is very clumsy, basically IMPOSSIBLE to even stand a chance to fight more then 1 enemy at once wich im used to do (10 years of SAMP), because I can barely run around to dodge bullets, I still dont understand how the guns work in MTA since sometimes they don't seem to do damage? and much more, might be because I have yet to learn all the other features and tips and tricks about the criminal world, and I don't like to spam the chat but when ever I have tried I can't say i've gotten much help at least in the crim chat :d
