Could there be a way to achieve this, perhaps a separate assignment giver or linked to the current assignments, where a faction group enters a "lobby" where they wait for another opposing faction to select the same option. This would load an instance, easily using the maps already in place too, where instead of npcs it is just a faction vs faction standoff for a goal.
Game types could include;
Ambush, a fight to the last man, the most basic form.
Assassinate, functioning like it does now, with one or multiple targets selected at random from each group.
Search and destroy, can also be applied, with one group defending the barrels and the other trying to take out what they can.
I'm sure there are plenty of other game types too, but the idea is that one side doesn't necessarily "win out" every time, there are different objectives (body/barrel count, time held etc) that would be evaluated upon "completion" (time runs out, one group leaves or is wiped etc), the result would be the usual xp, caps and rep reward (or possible complete failure), and the cooldown timer would begin.
There would however have to be no way to get back into after death like one can currently with assignments. If you died you are out for the rest of that mission, you just have to hope one of your buddies gets your gear

. Those who had died would have to wait until the assignment was fully finished before handing it in with the rest.
There could be team number limits and minimums etc and they could be scaled much like the A-SSS system. Allowing bigger groups to wait in higher tier lobbies for other big groups.
Does this sound reasonable at all or outside of what you are trying to achieve?
