From Dangerous Covenants
The one rank in a combat skill and one rank in a non career skill... I had the idea that they could double up, say a spy:infiltrator could then start with free 2 ranks in Brawl OR Ranged light and tested it in ogg dude's character generator and it works. Anyway that's a 10+15 xp = 25 xp benefit compared to a human 2 different 1 free ranks in non career skills 10+10=20xp. And a combat character is probably going to want to start with a 3 in agility, and they'll want to increase the willpower back to at least 2 and assuming that, they're just as good as humans on that front. so it's a situational 5 xp bonus over humans.
