We talked a little bit about this earlier when Celestalon mentioned that Master’s Call and Spirit Bond would not work if a survival or marksmanship hunter chose the Lone Wolf talent. Yesterday, he talked a little more about this subject. In short, Blizzard is OK with some talents being made useless by choosing another (as long as the player can still choose between two in any given talent tier).
@Lolzormon All of which are on different rows, ensuring a choice on each row.
