My halfling warrior alt has more stamina than I need now (219 unbuffed) and in group situations (and awkward solo situations) I often want more dex but never worry about stamina. In raid situations I'm obviously maxing both stats... I put my starting points into stamina.

not putting your starting points into dex is the casual move. If you're a long term player (and want to participate in the raid scene for like a year or more), put your starting points into dex, even for a race like halfling....
