Second: I expect that this will be instantly dismissed, but it seems like a good idea that Green Ronin offer alternatives to those powers and bonuses that refer to Exploration and Roleplaying stunts. I don't know whether we're alone in this, but our group finds those game features slightly abhorrent.
Same here. We ignore these two types of stunts altogether. Thus we removed the new talents "Intrigue", "Observation" and "Oratory" as well as the rogue's level-6-class power, and we changed "Carousing (Master)". For us, it works better this way.
