Ability to claim territory, plus points for being in said territory.
Owning a non-meta territory, like subs, gives you more XP therefore more incentive to base in harder to defend locations.
Allow orgs to declare war for an attempt to gain control of that area.
Encourage the creation and usage of legal/crafting orgs (@Brinch *wink*) where you can buy materials for less tax or even tax free after a certain level by crafting x amount of weapons and/or buying x amount of materials first. Or getting a official company registration for a high fee.
If abuse is a problem then make it so that you can only sell and give the weapons to non-org members and not use them yourself but I doubt this would create any problems. If you happen to find or craft a gun by you, make it so you can use it a week (IRL days) later to counter it and encourage mass crafting if there is tax involved.
Better Bait - less chance to hook trash, leading to a greater yield overtime.
Trash Collector - less chance to hook fish, leading to a greater yield of trash overtime.
Higher Rod Count - more rods are place-able by one person.
Fishing Expertise - catch fish faster & at a more consistent rate.
Fishmonger - sell fish for a higher price &/or with less tax applied.
Knowing the Waters - better chance to catch higher quality fish (could lead to a fishing update in the future which adds more variety in the fish we can catch).
Will probably add more as I think of them, reply with any ideas you lot have.
