Jan 30th 2009 12:21AM As a former raid healer through BT and SWP, the addon Getting Things Healed (http://www.wowinterface.com/downloads/info10457-GettingThingsHealed.html) was indispensable for the logistical aspects of assigning heals, allowing you to focus more on evaluation / tweaking.
VERY highly recommended.

It is incredibly nice that they added this for when you get a flying mount, as one of the benefits of flying mounts is being able to cruise along to your destination without worry about aggroing mobs. However, this is somewhat hampered when your pet insists on running along directly underneath you on the ground when you're flying, resulting in my pet usually dieing from aggroing entire camps or running off of cliffs if I forget to dismiss them.
