So my bad, I misread the goblin blog. I assumed it meant it the 3rd boost was unique to goblins, but it meant based on your unique ancestry you gain a 3rd stat boost. Hobgoblins gain the 3rd boost to con, ect.
So are all races getting 3 ability score increases? In the goblin preview that said goblins are unique and get a 3rd ability score boost, but dwarves and elf get a 3rd ability boost as well. Or have a misread something. If all or nearly half the races get a 3rd ability boost, I wouldn't really call that unique.
