I agree. It needs some tweaking. It is also a feat that literally has no benefit by itself. With the half-elf and half-orc hertiage feats, you at least gain two benefits from your parent race. It would stand to reason that taking this feat would at least give you one non-biological heritage feat. (The Adopted Trait from 1e gave you a free trait from your adopted race.) A human raised by halflings could have some of their luck rubbed off on her. A dwarf raised by gnomes might have picked up an animal friend that has followed him into his adulthood. Picking these abilities up at 5th level seems empty and you have to spend an additional general feat to gain access to an ability that is mostly for flavor and story.
Bottom line, this feat should be a Heritage Feat that any race can take in addition to giving you access to the heritage feats, it should give you the language of your adopted race (the obvious one) and maybe also trained in one related skill, kind of like how Half-Elf and Half-Orc Heritage Feats are set up. Otherwise, I think they should just give you a free Heritage feat from your adopted race right off the bat. Otherwise, what is the point?
