I really liked this one; Fluff AND Crunch. I would like to see more of this sort of article in Dragon, but ones like these have been few and far between lately. The constant stream of fluffy "puff piece" articles is making me question why I still subscribe.
Anyway, I have a player in my game that could have made good use of these themes, but that game started a year ago, so I just made something up instead. I'm pretty happy with what I came up with, and I think my player is too, but it would have been cool to not have to eyeball balance concerns.
