There are also rumours that your server might crash if you force guns too much, but haven't seen it happening so Im having hard time believing in it or I just haven't forceclassed enough lol.
Forceclasses are fun imo, but usually you can't use them in maps that has VIP. If you force a gun to VIP, will round end immediately when someone dies. ( Oh yet another place where to dream about new version of Hospital with no VIP and SF guns nor RPG's, maybe night- or a bit darker map and briefcase as objective
) I have made a tool which allows you to create totally random scripts without forcing VIP, the tool has instructions how to run it. I know it's a bit clumsy when compared to desktop application, but if you have two displays, you can open the tool and notepad to your secondary display and play with your main one, then creating and saving new scripts can be done in 10 seconds.
Here's the tool
About not being able to force on VIP maps and such, that's why there used to be modified map files, with weapon classes being re-assigned automatically. I remember playing Dusk with sf weapons on FUBAR server, back on 2.6.0.
I've also heard the stuff about forceclassing being able to make a server crash, however it has never happened to me. Was doing it from time to time years ago, back when my server was constantly online, filled with about 20 people and never experienced any issues.
