“This means, of course, that some groups might choose to have in-game xp earnings usable only for gameplay uses, and discovery points, awarded between sessions usable only for long-term character advancement.” I think is the relevant passage. He states that he doesn’t personally like that (of course, that’s why it’s not the official rule). Might be trivial. As I said, I’ve read that it is a popular complaint. I have no play experience with the system to confirm or deny, just a read through some time ago. 🙂
