Well I have 3 suggestions for the Server
1.Some houses and businesses should be added to be bought to make the server a little more interesting
2.Faction Leaders.Well,it shall be chosen an leader for every faction (Police,Army,Detectives etc.),and an Co-leader so they can start wars (Check Idea 3 )
3.It shall be added an command /startwar (faction) (amount)..The lider of the faction can do (Let's suppose that I'm the lider of police)..and I write /startwar detectives 200.000$...And,if the detective leader or co-leader accepts it's gonna be an war..So,the first faction who scores 50 kills to the rival faction,wins the 200.000$ from the loosers...(+it shall be added an command /warinfo where you can see how many points each faction scored)
Hope you will like it and if it will be added I will be very happy
