I like everything but the ability to buy the guns and scopes you suggested and the bank speed increase. Maybe instead of being able to buy them make them craftable or added to/increased spawn rates in gear loot pools for events when someone with the talent starts it? Instead of a bank speed increase maybe an increased payout or something? Maybe cops need to spend more time to disable it.
If we wanted something buyable an ASP would be way more reasonable than a mar10. Vehicle wise, qilins with doors, armed prowlers, and unarmed hurons and ghosthawks would be reasonable things to added to the list.
Mar10s are ass btw and very situational at least when I use them on other servers, not sure how good they are against Ifrit front glass with Asylum's nerfed glass.
Also this is a very linear tree compared to the branching cop prestige and bounty hunter honor trees so it's not a perfect comparison
