On one hand BL sounds good, but its not needed for hunter, since raids are usually filled with at least 2 shamans (1 of them being resto) and 2 mages, and its not like you can stack that buff (unless they changed something).
Kings on the other hand sounds more reasonable, since palies will just give other buffs like Might or Wisdom.
I like "Supporter class" approach from blizzard, yet they are to late and making 1 spec as a supporter wont change anything. Maybe next expansion...
