I am DM'ing in a rotation with 1 or 2 other DM's (I'm Book 1 & 4, if not more due to one DM being busy with school) and we're playing with 4 active PC's.
They definitely are diverse and we're just starting on the Missions portion after the first week of Rebellion. After a few random encounters they've definitely realized that it's not all about 'killing the bad guys' and for some I think it's killing them inside. ^_^
They've strayed a bit off track to what I originally planned (what group hasn't?) but luckily the missions sprawl all over Kintargo so I'll just make adjustments accordingly. The biggest issue is that even though I've given them good hooks to bite, they still aren't sure of what they should be doing. I don't want to break the immersion so I spend my off-time coming up with things that could help solidify that for them.
Last bit, I am a huge fan of The Flash on CW, so at the end of each of my sessions, I run a little teaser bit to help paint a better picture of what goes on in other parts of town (vaguely) and the aftermath of any encounters. For example, they encountered an Asmodean patrol and subued them after getting information from them, leaving them in an alley. The teaser was a pedestrian walking by and noticing them left in a very un-church-like position and ran frantically back out of the alley and down the street, while a dark hooded figure slowly passes the alley, turns its head to see the sight and slowly follows the pedestrian.
I've got them on the edge of their computer chairs :)
