Forcing level 3+ gangs to have a gang safe that in return will only make gangs to keep below the limit money in gang if they don’t want to participate kinda makes no sense.
Don’t include suggestions on how gangs will have to change their ways with their gang accounts, that’s none of your business.
If gangs see value and want to participate in GRs they will need and have a safe. If not they simply wont’t have it
It would be a fair trade off though. If you don’t want to have a safe, then you should not be able to use the gang bank.
Adding to that, it is already similar to what you described, gangs currently don’t participate GRs because they choose the safe route of not having a gang safe at all because they see GR as an activity shrouded with the misbelief of report wars and such. By forcing them to have a safe, it would prevent the luxury of having tens of millions of dollars sitting in a gang bank with no threat, and consequently maybe entice them to try out GRs?
Personally, I like the activity of GR, and I dislike gangs that keep the activity dead by choosing not to have a safe at all. I specifically pointed out level 3+ gangs because they spawn with sufficient weaponry to be able to defend their safe.
