Yeah, but bounties, etc. to me either fall into the mission reward or selling to shop groups. Just that some items/professions have "specialty" shop that increase the credits into the game.
Similarly, the only way credits exit the game (permanently) are buying items from shops (basic advancd, trader, bounty buyers, npc, etc., from gmi sales commissions, from rents, and from players deleting toons with credits still on them. (even inactive accounts can be activated and the credits restored).
Sorry I was not clear on what constitutes a "shop" but was referring to any npc, store, or kiosk where the credits are exchanged for an item or service to a funcom managed provider.
But this really is the heart of the matter for the new rents. New (and probably many returning toons) simply do not have the capability without endless farming on RK or pearl farming in sl of generating the monthly rents. Because yes, it seems that with the massive credit sinks cities have become, more people are going to decide it isn't worth it. And, eventually the surplus built up over the last decade will be gone as well. There really needs to be some determination by funcom on the credit inflows and outflows so they can be reasonably balanced.
I also disagree with making a pivotal aspect of the game a credit sink. Would much rather see "luxury" kiosk developed that would be unreasonably priced that would allow people to make their toon unique. Two items previously mentioned in other threads: Turn the cosmetic surgeon in the hq into a simplified version of the law enforcement sketch program where people could design a unique face. Then charge them massive amounts for the plesure. Second, do something similar with the social clothing in Muiir. I know many people would pay for ability to make their toons more identifiable/unique.
