I love how, even on Expert difficulty, I can progress my character power through Renegades activities, even if it's just by a few points. Good job there Bungie! Now if you can bring that to the rest of the portal system, that would be fantastic! Let every player feel like they are progressing, even if it's only a little on the lower difficulties. And if people want more progression or try for better tier loot, then they can choose to ramp it up.
