Hey Kelton, it's a good idea this topic. Let me address some things in my mind which I miss, being a 2010+ player.
Economy
The one problem with these days is the vehicles and extreme economic fluctuations. For example: Level 5's with have the dream cars which, in 2012 for example, you'd see a Level 70+ having. By this I mean: Infernus, NRG-500, Sultan, Maverick, Sparrow etc. I believe the solution to this, is to "unlock" these things via hard work. E.G: "Getting rank 3+" in a faction would give you the means to be able to drive better cars. Other than that, there's not much we can do to delete the money off the server except auctions.
DM'ers / Civilian Armies:
I made this proposal about half a year ago, to create a "Deathmatch" server for these fools. Let the civilians who come to B-Zone to DM, play on a server where they can stretch their feet back all the way and have fun where it's legal. To make: tdm.b-zone.ro:7777 and problem solved. Anyone who makes DM, you can just /kick them and send them there. It's a good way to keep the players happy and offer a peaceful solution.
TRUCKERS TRUCKERS TRUCKERS TRUCKERS MAAAA
Please send them in another virtual world. Lol. No more to say about it.
Factions
I think it's a good idea to add much more factions. There's not enough to cover a 1000 player base. Why not add colors for Secondary jobs. E.G: Garbage men, they can have a nice dark green color at their name. So they feel like they're achieving something too. Rewarding the civilians will help more.
More events
Try adding more automatic things. Like:
Duel Arena (1v1 battle)
Sniper Arena
Cops Vs Robbers Arena
Many different Arenas to attract the players to do something else than just Paintball. Split up the different arenas and make a massively diverse server. It will be easy to script and will be good.
I'm giving too many suggestions at the wrong section, but yeah, +1 if you're with me boys and girls.
