That would've been good. We could remove maybe half of the fetch quests and replace them with a few better-fleshed-out sidequests -- maybe something comparable to the Cerberus quest line in ME1. There might be something about war profiteering (Paragon/Renegade choice at the end -- shut down the operation, or make them funnel their profits into the war effort), and maybe a quest to recover a Prothean artifact from a well-armed private collector who doesn't want to part with it (think Donovan Hock). They could also have expanded the Sanctuary mission into a larger quest line -- when I heard people talking about it, it was obvious to me that it was at least a scam, and very possibly much worse, but the game didn't let me pursue it until near the end.

As for Leng ... make him a bit more mature, a bit more capable, and a bit more *present*. Every time Cerberus has a major operation, put Leng visibly at the head. Of course, that wouldn't really be very compatible with his role as an assassin, so maybe the character concept would have to be changed a bit. Alternately, have him very visibly assassinate some important people, then lay a trap for Shepard when the Commander comes after him. That would get him more respect from me.

Having Harbinger ASSUME DIRECT CONTROL a few times would be good too -- start introducing it at the beginning of the Earth missions, since he's there in close proximity. Harbinger ASSUMES DIRECT CONTROL of the occasional Husk/etc.; it would have to be as dramatic as the transformation from a Collector to a Harbinger-Collector, just make the affected enemy glow, gain barriers and armor, and focus killing Shepard to the exclusion of all else. It'd be a good way to add variety and make the Earth missions less of a oppressive slog.
