How would it benefit the server: This would help the server run alot smoother. I think that players shouldnt need to wait 5 minutes to raid a base after they switch jobs. So i think that the time should be changed to a shorter amount of time. It would also cause players to get warned less often.
If I'm understanding what you're getting at here the issue is the time for people to switch jobs.
The thing about that is there always needs to be an ample amount of times to avoid job abuse. The time use to be 10mins now it's only 5 so we have shortened it a lot.
You have to thing of it in different situations so say we lowered it to idunno two mins.
Player A just spawns in he changes job to a drug dealer goes bases gets killed and gets up back at spawn. He sees that you just got a 1mil hit and starts walking back to his base he sees you so he switches to Hitman and then kills you. He now takes the other 40-50secs to walk back to his base and he can now switch back to drug dealer.
It just doesn't make it fun for a lot of people when people can just switch job like it's their cloths because there is even less role play in a already relaxed environment. I understand where you're coming from but I just think maybe you should plan your jobs or what you're going to do a little better.
