Big fan of the change from Motivations to Weaknesses, and tying those into Advancement and potentially overcoming the Weakness! I feel like that could lead to some really fun roleplaying moments.
Echoing some other posters, I'd love to see the Halfling and Dwarf Kin abilities modified to be similar to the Wolfkin where there is both an in and out of combat usage. Perhaps the Dwarf's ability can be expanded to those who have harmed or wronged you in the past. I also like another the idea of halflings getting a boon to use Sneaking if they are in small or hard to reach places. So a halfling sneaking through a manor might choose to hide in some cabinets or in a crate rather than just in the shadows.
