Stagger your freezing traps/intimidation on Round Robin, save your BW TBW till you get 1 or more on you,and don't forget your insignia of the horde.
(also helps if you can get a real person/healer to back you up,Druids are my favourite)
Don't forget to run and play your lead Hunter with track hidden when your static,(much love from Rogues on this one).
Gear is really important,but you can still expect to lose one character to a well specced warrior.
Dump as many serpent stings on them as soon as you can,and watch for AoE mages.
A favourtite AV strat is to charge in a warrior with a healer get you focused on him then blink in a mage and AoE you to oblivion,seed of corruption somtimes too.
(oh and lastly rogues like to pluck at your trailing char with sap or similar,hoping you'll ride off and leave him stranded)
IF you have Track Hidden up just ride back and do figure 8's till you find him,then go all animal and stuff on him,(how much love from Rogues for this one ? loads :thumbsup: ).
