Shamrock, I undestand your concern with the designators. I was really concerned about this as well. While I think that the weapons in ented the unknown could have (and easily can) have generic names, such as sniping blaster, they don't scream better weapons. I'm hoping dangerous covenants adds in some more weapons like a 'stouker concussion rifle' - new types if weapons, where the name is irrelevant.
As to correllians getting seperate stats I have a wait and see. At this point, I'm hoping to see the the same as core book humans, -20 xp and have an ability choose one skill from pilot (either), mechanics or vigilance. This skill auto generates 1 advantage.
