[Shujin]

For Lone Wolf:
I'd say if we do something like that, the bonus is gone when party size above one, how you have written it, even with full party they still gain 5 armor. Soo nah. Suddenly everyone being lonewolf and all get bonuses even with full party=Against the theme.

Aerial Mastery:
Thats honestly something I always thought Corbies or flying races should have by default. Maybe a toggle skill.

All Flight:
Good joke.
