45 hunter beast spec solo is no problem.
I just killed Fozruk then mage, then the other two weren't doing any damage to the pet. 
Used Multi-shot, then explosive trap, fiegn death, beastial wrath, rapid fire, healed pet till he dropped, wasnt instant but was no biggy, I had over half mana, full health and pet was about half health, the other 3 pip squeaks were crap.
Wasn't the easiest way I guess but it worked, prolly shoulda killed mage first =)
