I've got a couple concerns with the second edition of Pathfinder. I'll try to keep them brief. This is also in order of discovery.
1. Ancestry feats both mechanically sound and broke. Here's why. Genetically the humanoid species are still close enough on the tree of life where interbreeding is still not only viable but those children are capable of reproducing. How it's wrote, mechanics is sound, how it's implied is you had an elf or orc ancestors that snuck in the family tree on both sides and those recessive genes happened to activate in you. If it was for background of your character, that's fine for background, not as a feat. It'll be like taking a feat for the sorcerer's bloodline, your sacrificing a feat for maybe a bit more awesome than base human. Not to mention that humans, elves, and orcs are still capable of interbreeding in starfinder.
2. Pages 5 and 6. It's not needed. any and all problems would be resolved within the group, not the company. There's several discussions on that topic so I'm not going to start a broken record. I also play white wolf/onyx path world of darkness series, there's a tweet they used that I'm going to imply for all the possible flak.
My recommendation is bring back half elf and half Orc as proper player races, and repurpose page 5 and 6 for goblins as a PC race.
