I have a lot of experience with hunters.. and I've 4-boxed 19 hunter twinks quite a bit, and um.. well. Here's what you would get:
  • Awesome levelling
  • No problem with 5-mans
  • Awesome for BGs (boar charge x4, need not say more)
  • Useless for heroics without tank and healer help
  • Probably useless for arena due to no off-healing, low survivability
