I'm not sure I agree with any of IGN's selections.
I think it would be nice to have some non-combat locations where both factions intermix. Something along the lines of Voss-Ka on Voss, but with a healthy dose of espionage and intrigue thrown in. I think Bioware really missed a trick there. They could have gone for a whole swathe of missions that relied on subverting the other faction's standing purely through dialogue and other non-combat missions. But I guess the majority of their playerbase get bored if they go more than a few minutes without killing something.
