If you've played the game for a rather long time, like me, those resources are not too hard to come by. I don't think they intend for specters to be used EVERY mission, but when the mission gets tough, maybe during boss fights, and my personal favorite, Stalker ganks. Use them disparingly, since they steal your XP too.
