Yeah, those 15 seconds of intense work are kinda advanced for a new Hunter. But there is a solution if you want Crippling Poison. Tame a nice Rogue. So far, I've only managed to do this to an Undead Rogue. Usually comes with Prowl, Crippling and Deadly Poison. The disadvantage is that the Dash is on a five minute CD. The Undead variety also has a nice ability to regain health by eating Humanoid mobs you've killed, and break Fear. No need for BM Specc for that if you get the Undead Rogue pet.
They do have this ugly tendency to aggro stuff and suddenly vanish, dumping all the Aggro on you. Can be rectified with Feign Death.
And I can only wish that I was joking right now. Our guild has very friendly relations to a Horde guild, and one of their Rogues in particular. He has helped me quest on several occasions, and also helped me kill Bots and ********* of my own Faction. The standing joke is that I am the only Hunter on the server that has tamed a member of the opposite faction.
