Alright, one more time... coming at it in a new way:
It's the same advantage mundanes have over magicians.
Yes, mundanes give up sorcery, summoning, the entire astral plane, and more. It's a huge penalty to play a mundane, right?
Yes, but the upside is mundanes get to ignore the entire E row on the priority chart, as that's where magic goes.
Same thing for humans. They don't stress over what to put in E, but now also D. Human mundanes only worry about how to spend A-C on Attributes, Skills, Resources. There's no "hard" choice on the priority chart for a mundane human. THAT is the big racial advantage. (admittedly, this main human advantage would get marginalized in a point buy chargen system. So I'm not sad there is no point buy chargen yet.)
Human magicians/technomancers have less of a racial advantage than mundane humans in having only 1 potential dump priority rather than a guaranteed 2, but Awakened/Emerged humans still have their dump priority advantage vs Awakened/Emerged metahumans who have no dump choices whatsoever.
