I had idea... not uber sure if good - surely will be blessed by some but I see what problems it might bring: Stackable leases of weapons.
You know how leases work now, right? You rent weapon for cash for 10 days, period. If you rent that weapon again, you will extended that time again to ONLY max 10 days.
What if that would be stackable? You lease weapon for 10 days. Then for 20 days. 30, 40 etc. etc. - limit is just budget.
Now. I see problem - free weapons are supposed to be struggle,
