Some more general play questions - on the Revised Action Economy itself as well as your innovations upon it (primarily the "passive act" I believe).
Was it a problem that low level PCs could attack three or four times per round?
What about the NPCs?
How do you handle creatures with natural attacks? Does it matter how many they have? For example creatures with 2, 3, 5, or 8 natural attacks?
What is the impact of getting rid of "tertiary" attacks? By this I mean the second iterative in the old system (at -10) as one might expect it to translate into the new system (at -10).
What are the exact rules for the 5-foot step? For example, if I have used 1 act to move this round, can I save my passive act for a 5-foot step? (This is prohibited in the regular rules).
