It reads like you've only got one hunter and one druid - if that's correct, really the main thing to do is to get a Greater Fleshripper or something with Screech as your hunter's pet. As was said, that is an AOE threat generator. With the talents in BM for armor and health, and training the pet in the skills for armor and health, you should be able to send your pet in to start and then burn each target down individually, healing your pet and not drawing aggro.
