So, I've been throwing something back and forth with a coworker of mine. Simply put, if DLC was released which required an active sub, would new/alternative guild traders be offered in new zones? Additionally, if someone doesn't actively sub, yet the GM does, should it be allowable for non-subs to continue benefitting from the new location if the guild won the bid?
I gave it some thought and decided to see what others thought. Based on how the game is built right now, it would be safe to assume that new trader locations would be present in the new DLC zones. Say someone sub-hops until they have gotten what they can out of the content, then unsubbed.
All this leads me to believe that we probably won't see a DLC requiring subscription but rather a simple purchasable DLC. Then again, they could totally revamp the trader/economy system and blow this theory out of the water...
