It would be nice to be able to do 3-man fireteam activities with anywhere from 3-6 people while scaling the opposition. Patrol (and things like Court of Oryx) are obvious places where this kind of request is not uncommon, but someday I'd like to be able to load up a strike or CoE when there are 3-4 of my friends on and we'd all like to play together. Scaling would clearly be a problem, but maybe that could be handled by adding an extra negative modifier (like Fresh Troops / Ironclad / Exposure) for having 4 or 5 players, and a second negative modifier for having 6.
