I'd suggest a change in scoring. As it stands, 4 1000 pt. traits are worth 4 points, while 1 4000 pt. trait is only worth 1.
Reward Traits -- 500 to 1000 points -- 1 pt.
1000 to 2000 points -- 2 pt.
2000 to 3000 points -- 3 pt.
3000 to 4000 points -- 4 pt.
Aspiration Traits -- 5 pt.
That way if GTW adds more low-point reward traits, there will be less of an advantage for people who have it.
