Don't make this too hard...

Before you reach a certain gear level, you probably want to burn all your Art of War procs on Flash Healing your tank or your team. A macro that assists your main and casts FoL is useful, as is a simple /cast [target=yourtankhere] Flash of Light macro.

Ideally, you use a click-to-heal addon with a passthrough/mouse-repeater capability so you can manage healing with the mouse and other movement/attacking with keyboard.

As you gear up, you can make exorcism macros to burn AoW procs on the extra DPS of exorcism. Since it has a cooldown, you'll have AoW procs available shortly again to flash heal whoever needs it.

It's not the end of the world if some of your gang doesn't have an AoW proc ready and they actually cast a FoL, and if you're chasing someone down in PvP, only the characters with AoW ready will be able to cast on the move anyhow.
