I would suggest allowing players to transfer their items via the Storage Transfer System regardless of the Settlement’s controlling faction.
HOWEVER.
- Transferring between Settlements owned by your faction would be free.
- Transferring outside of your faction would cost coin (formula would be what ever they use to calculate the fee right now)
- At least 50% of the ‘transfer fee’ is given to the controlling Company’s coffer to pay for town upgrades
These changes should still place (and imo even more) importance on capturing zones. Especially if a zone’s settlement has very high-tier crafting stations; who wants to schlep a bunch of crafting materials if you can have them transported.
((Example: I was looking to make Silk. I had over 1.5k Silkweed. It was going to cost me over 1000 gold to transfer them from Brightwood to Weaver’s Fen. Imagine if I had and WF wasn’t owned by my faction…nearly 500 gold would have gone to the owning company.))
