Heres a quick tip that my guild uses to make trash quicker for eagle boss.
When you are facing the scout guy that starts the event, turn around and run towards the pool. Have everyone stand in the pool except for the tank and a hunter. Have those 2 stand next to the cliff by the pool. Then have the hunter target the tempest, and send his pet in, after the pet gets aggro pull him back. You should pull the tempest, and the 2 adds nearest him. After you kill those you can kill the rest of the people without any birds or guardians.
Sorry if this is a repost, pic of the spot coming soon.
EDIT: Might work with warlock pet too.
P.S. My paint skill is pro.
